bisect: fix off-by-one error in `best_bisection_sorted()`
After we have sorted the `cnt`-many commits that we have selected, we
place them into the commit list. We then set `p->next` to NULL, but as
we do so, `p` is already pointing one beyond item number `cnt`. Indeed,
we check whether `p` is NULL before dereferencing it.
This only matters if there are TREESAME-commits. Since they should be
skipped, they are not included in `cnt` and we will hit the situation
where we set `p->next` to NULL. As a result, the list will be one longer
than it should be. The last commit in the list will be one which occurs
earlier, or which shouldn't be included.
Do not update `p` the very last round in the loop. This ensures that
after the loop, `p->next` points to the remainder of the list, and we
can set it to NULL. While we're here, free that remainder to fix a
memory leak.

slash.
This double slash is not only unintentional, but is allowed by the POSIX
standard to have a special meaning. And most notably on Windows, it
does, where it refers to a UNC path of the form `//server/share/`.
As a consequence, afore-mentioned `rev-parse` call not only looks for

to access a server called `HEAD`. Let's simply avoid the unintended

mingw: add experimental feature to redirect standard handles
Particularly when calling Git from applications, such as Visual Studio's
Team Explorer, it is important that stdin/stdout/stderr are closed
properly. However, when spawning processes on Windows, those handles
must be marked as inheritable if we want to use them, but that flag is a
global flag and may very well be used by other spawned processes which
then do not know to close those handles.
Let's introduce a set of environment variables (GIT_REDIRECT_STDIN and
friends) that specify paths to files, or even better, named pipes (which
are similar to Unix sockets) and that are used by the spawned Git
process. This helps work around above-mentioned issue: those named
pipes will be opened in a non-inheritable way upon startup, and no
handles are passed around (and therefore no inherited handles need to be
closed by any spawned child).
This feature shipped with Git for Windows (marked as experimental) since
v2.11.0(2), so it has seen some serious testing in the meantime.

commit 657343a60 (travis-ci: move Travis CI code into dedicated

The reason is that P4 and Git LFS binaries are not installed to a
directory in the default $PATH, but their directories are prepended to
$PATH. This worked just fine before said commit, because $PATH was
set in a scriptlet embedded in our '.travis.yml', thus its new value
was visible during the rest of the build job. However, after these
embedded scriptlets were moved into dedicated scripts executed in
separate shell processes, any variable set in one of those scripts is
only visible in that single script but not in any of the others. In
this case, 'ci/install-dependencies.sh' downloads P4 and Git LFS and
modifies $PATH, but to no effect, because 'ci/run-tests.sh' only sees
Travis CI's default $PATH.
Move adjusting $PATH to 'ci/lib-travisci.sh', which is sourced in all

a subdirectory.
This isn't a very large regression, since it is not that likely that the
exec command will run a git command, and even less likely that it will

system which uses git-describe to find the current version of the build

That's shorter and easier.
While at it correct the length of the second substring in a comment.

merge-recursive: check GIT_MERGE_VERBOSITY only once
Get rid of the duplicated getenv('GIT_MERGE_VERBOSITY') calls with the same
constant string argument. This makes code more readable and prevents typo in

status: add option to show ignored files differently
Teach the status command more flexibility in how ignored files are
reported. Currently, the reporting of ignored files and untracked
files are linked. You cannot control how ignored files are reported
independently of how untracked files are reported (i.e. `all` vs
`normal`). This makes it impossible to show untracked files with the
`all` option, but show ignored files with the `normal` option.
This work 1) adds the ability to control the reporting of ignored
files independently of untracked files and 2) introduces the concept
of status reporting ignored paths that explicitly match an ignored
pattern. There are 2 benefits to these changes: 1) if a consumer needs
all untracked files but not all ignored files, there is a performance
benefit to not scanning all contents of an ignored directory and 2)
returning ignored files that explicitly match a path allow a consumer
to make more informed decisions about when a status result might be
stale.
This commit implements --ignored=matching with --untracked-files=all.
The following commit will implement --ignored=matching with
--untracked=files=normal.
As an example of where this flexibility could be useful is that our
application (Visual Studio) runs the status command and presents the
output. It shows all untracked files individually (e.g. using the
'--untracked-files==all' option), and would like to know about which
paths are ignored. It uses information about ignored paths to make
decisions about when the status result might have changed.
Additionally, many projects place build output into directories inside
a repository's working directory (e.g. in "bin/" and "obj/"
directories). Normal usage is to explicitly ignore these 2 directory
names in the .gitignore file (rather than or in addition to the *.obj
pattern).If an application could know that these directories are
explicitly ignored, it could infer that all contents are ignored as
well and make better informed decisions about files in these
directories. It could infer that any changes under these paths would
not affect the output of status. Additionally, there can be a
significant performance benefit by avoiding scanning through ignored
directories.
When status is set to report matching ignored files, it has the
following behavior. Ignored files and directories that explicitly
match an exclude pattern are reported. If an ignored directory matches
an exclude pattern, then the path of the directory is returned. If a
directory does not match an exclude pattern, but all of its contents
are ignored, then the contained files are reported instead of the
directory.

t0000: check whether the shell supports the "local" keyword
Add a test balloon to see if we get complaints from anybody who is
using a shell that doesn't support the "local" keyword. If so, this
test can be reverted. If not, we might want to consider using "local"
in shell code throughout the git code base.

files-backend: don't rewrite the `packed-refs` file unnecessarily
Even when we are deleting references, we needn't overwrite the
`packed-refs` file if the references that we are deleting only exist
as loose references. Implement this optimization as follows:
* Add a function `is_packed_transaction_needed()`, which checks
whether a given packed-refs transaction actually needs to be carried
out (i.e., it returns false if the transaction obviously wouldn't
have any effect). This function must be called while holding the
`packed-refs` lock to avoid races.
* Change `files_transaction_prepare()` to check whether the
packed-refs transaction is actually needed. If not, squelch it, but
continue holding the `packed-refs` lock until the end of the
transaction to avoid races.
This fixes a mild regression caused by dc39e09942 (files_ref_store:
use a transaction to update packed refs, 2017-09-08). Before that
commit, unnecessary rewrites of `packed-refs` were suppressed by
`repack_without_refs()`. But the transaction-based writing introduced
by that commit didn't perform that optimization.
Note that the pre-dc39e09942 code still had to *read* the whole
`packed-refs` file to determine that the rewrite could be skipped, so
the performance for the cases that the write could be elided was
`O(N)` in the number of packed references both before and after dc39e09942. But after that commit the constant factor increased.
This commit reimplements the optimization of eliding unnecessary
`packed-refs` rewrites. That, plus the fact that since cfa2e29c34 (packed_ref_store: get rid of the `ref_cache` entirely,
2017-03-17) we don't necessarily have to read the whole `packed-refs`
file at all, means that deletes of one or a few loose references can
now be done with `O(n lg N)` effort, where `n` is the number of loose
references being deleted and `N` is the total number of packed
references.
This commit fixes two tests in t1409.

Otherwise uninitialised 'struct stat st' variable is used later in case of

file mode ('S_ISLNK(st.st_mode)' check) or size ('xsize_t(st.st_size)').
