rust: build correctly without GNU sed

t5563: add missing end-of-line in HTTP header
In t5563, we test how various oddly-formatted WWW-Authenticate headers
are passed through curl to git's credential subsystem (and ultimately
out to credential helpers). One test, "access using basic auth with
wwwauth header mixed line-endings" does something odd. It does not mix
line endings at all (which must be CRLF according to the RFC anyway),
but omits the line ending entirely for the final header!
This means that the server produces an incomplete response. We send our
final header, and then the newline which is meant to mark the end of
headers (and the start of the body) becomes the line ending for that
header. And there is no header/body separator in the output at all.
The headers themselves are produced from the custom-auth.challenge file
we write in the test (which is missing the final CRLF), and then the
header/body separator comes from our lib-httpd/nph-custom-auth.sh CGI.
(Ignore for a moment that it is producing a bare newline, which I think
is a bug; it should be a CRLF but curl is happy with either).
Older versions of curl seemed to be OK with the truncated output, but
the upcoming 8.18.0 release seems to get confused. Specifically, since 67ae101666 (http: unfold response headers earlier, 2025-12-12) our
request to the server fails with insufficient credentials. I traced far
enough to see that curl does relay the header back to us, which we then
pass to a credential helper, which gives us the correct
username/password combination. But on our followup request, curl refuses
to send the Authorization header (and so gets an HTTP 401 again).
The change in curl's behavior is a bit unexpected, but since we are
sending it garbage, it is hard to complain too much. Let's add the
missing CRLF to the header. I _think_ this was just an oversight and not
the intent of the test. And that the "mixed line-endings" really meant
"mixed continuations", since we differ from the previous test in
continuing with both space and tab. So I've likewise updated the test
title to match that assumption.

t5551: handle trailing slashes in expected cookies output
We check in t5551 that curl updates the expected list of cookies after
making a request. We do this by telling it to read and write cookies
from a particular text file, and then checking that after curl runs, the
file has the expected content.
However, in the upcoming curl 8.18.0, the output file has changed
slightly: curl will canonicalize the paths it writes, due to commit a093c93994 (cookie: only keep and use the canonical cleaned up path,
2025-12-07). In particular, it strips trailing slashes from the paths we
see in the cookies.txt file.
This doesn't matter to Git, as the cookie handling is all internal to
curl. But our test is overly brittle and breaks as a result.
We can fix it by matching either format. We'll expect the new format
(without trailing slashes) and strip the slashes from curl's output
before comparing. That lets us pass with both old and new versions (I
tested against curl's 8_17_0 and rc-8_18_0-2 tags, which are
respectively before and after the curl change).
In theory it might be nice to try to future-proof this test more by
looking only for the bits we care about, rather than a byte-wise
comparison of the whole file. But after removing comments and blank
lines (which we already do), we care about most of what's there. So it's
not clear to me what a more liberal test would look like. Given that the
format doesn't change all that often, it's probably OK to stop here and
see if it ever breaks again.

t7800: work around the MSYS path conversion on Windows
Git's test suite's relies on Unix shell scripting, which is
understandable, of course, given Git's firm roots (and indeed, ongoing
focus) on Linux.
This fact, combined with Unix shell scripting's natural
habitat -- which is, naturally... *drumroll*... Unix --
often has unintended side effects, where developers expect the test
suite to run in a Unix environment, which is an incorrect assumption.
One instance of this problem can be observed in the 'difftool --dir-diff
handles modified symlinks' test case in `t7800-difftool.sh`, which
assumes that all absolute paths start with a forward slash. That
assumption is incorrect in general, e.g. on Windows, where absolute
paths have many shapes and forms, none of which starts with a forward
slash.
The only saving grace is that this test case is currently not run on
Windows because of the `SYMLINK` prerequisite. However, I am currently
working towards upstreaming symbolic link support from Git for Windows
to upstream Git, which will put a crack into that saving grace.
Let's change that test case so that it does not rely on absolute paths
(which are passed to the "external command" `ls` as parameters and are
therefore part of its output, and which the test case wants to filter
out before verifying that the output is as expected) starting with a
forward slash. Let's instead rely on the much more reliable fact that
`ls` will output the path in a line that ends in a colon, and simply
filter out those lines by matching said colon instead.

Bash will therefore literally link to a file or directory called `null`
that is supposed to be in the current drive's top-level `dev` directory.
Which typically does not exist.
The test, however, really wants the created symbolic link to point to
the NUL device. Let's instead use the `mklink` utility on Windows to
perform that job, and keep using `ln -s /dev/null <target>` on
non-Windows platforms.
While at it, add the missing `SYMLINKS` prereq because this test _still_

The MSYS2 runtime (which inherits this trait from the Cygwin runtime,
and which is used by Git for Windows' Bash to emulate POSIX
functionality on Windows, the same Bash that is also used to run Git's
test suite on Windows) has a mode where it can create native symbolic
links on Windows.
Naturally, this is a bit of a strange feature, given that Cygwin goes
out of its way to support Unix-like paths even if no Win32 program
understands those, and the symbolic links have to use Win32 paths
instead (which Win32 programs understand very well).
As a consequence, the symbolic link targets get normalized before the
links are created.
This results in certain quirks that Git's test suite is ill equipped to
accommodate (because Git's test suite expects to be able to use
Unix-like paths even on Windows).
The test script t1006-cat-file.sh contains two prime examples, two test
cases that need to skip a couple assertions because they are simply

t0600: fix incomplete prerequisite for a test case
The 'symref transaction supports symlinks' test case is guarded by the
`SYMLINK` prerequisite because `core.prefersymlinkrefs = true` requires
symbolic links to be supported.
However, the `preferSymlinkRefs` feature is not supported on Windows,
therefore this test case needs the `MINGW` prerequisite, too.
There's a couple more cases where we set this config key:
- In a subsequent test in t0600, but there we explicitly set it to
"false". So this would naturally be supported by Windows.
- In t7201 we set the value to `yes`, but we never verify that the
written reference is a symbolic link in the first place. I guess
that we could rather remove setting the configuration value here, as
we are about to deprecate support for symrefs via symbolic links in
the first place. But that's certainly outside of the scope of this
patch.
- In t9903 we do the same, but likewise, we don't check whether the
written file is a symbolic link.
Therefore this seems to be the only instance where the tests actually
need to be adapted.

Ever since fe53bbc9beb (Git.pm: Always set Repository to absolute path
if autodetecting, 2009-05-07), the t9700 test _must_ fail on Windows
because of that age-old Unix paths vs Windows paths problem.
The underlying root cause is that Git cannot run with a regular Win32
variant of Perl, the assumption that every path is a Unix path is just
too strong in Git's Perl code.
As a consequence, Git for Windows is basically stuck with using the
MSYS2 variant of Perl which uses a POSIX emulation layer (which is a
friendly fork of Cygwin) _and_ a best-effort Unix <-> Windows paths
conversion whenever crossing the boundary between MSYS2 and regular
Win32 processes. It is best effort only, though, using heuristics to
automagically convert correctly in most cases, but not in all cases.
In the context of this here patch, this means that asking `git.exe` for
the absolute path of the `.git/` directory will return a Win32 path
because `git.exe` is a regular Win32 executable that has no idea about
Unix-ish paths. But above-mentioned commit introduced a test that wants
to verify that this path is identical to the one that the Git Perl
module reports (which refuses to use Win32 paths and uses Unix-ish paths
instead). Obviously, this must fail because no heuristics can kick in at
that layer.
This test failure has not even been caught when Git introduced Windows
support in its CI definition in 2e90484eb4a (ci: add a Windows job to
the Azure Pipelines definition, 2019-01-29), as all tests relying on
Perl had to be disabled even from the start (because the CI runs would
otherwise have resulted in prohibitively long runtimes, not because
Windows is super slow per se, but because Git's test suite keeps
insisting on using technology that requires a POSIX emulation layer,
which _is_ super slow on Windows).
To work around this failure, let's use the `cygpath` utility to convert
the absolute `gitdir` path into the form that the Perl code expects.

diff-files: fix copy detection
Copy detection cannot work when comparing the index to the working tree
because Git ignores files that it is not explicitly told to track. It
should work in the other direction, though, i.e. for a reverse diff of
the deletion of a copy from the index.
d1f2d7e8ca (Make run_diff_index() use unpack_trees(), not read_tree(),
2008-01-19) broke it with a seemingly stray change to run_diff_files().
We didn't notice because there's no test for that. But even if we had
one, it might have gone unnoticed because the breakage only happens
with index preloading, which requires at least 1000 entries (more than
most test repos have) and is racy because it runs in parallel with the
actual command.
Fix copy detection by queuing up-to-date and skip-worktree entries using
diff_same().
While at it, use diff_same() also for queuing unchanged files not
flagged as up-to-date, i.e. clean submodules and entries where
preloading was not done at all or not quickly enough. It uses less
memory than diff_change() and doesn't unnecessarily set the diff flag
has_changes.
Add two tests to cover running both without and with preloading. The
first one passes reliably with the original code. The second one
enables preloading and thus is racy. It has a good chance to pass even
without the fix, but fails within seconds when running the test script
with --stress. With the fix it runs fine for several minutes, until
my patience runs out.

issues in various files. This commit addresses these issues to improve the
overall quality and consistency of the documentation.
* enforce consistent imperative mood in option descriptions

docs: clarify git-rev-list(1) --filter behavior
When using the --filter option for git-rev-list(1), objects that are
explicitly provided ignore filters and are always printed unless the
--filter-provided-objects option is also specified. Clarify this
behavior in the documentation.
