stash: don't show internal implementation details
git stash push uses other git commands internally. Currently it only
passes the -q flag to those if the -q flag is passed to git stash. when
using 'git stash push -p -q --no-keep-index', it doesn't even pass the
flag on to the internal reset at all.
It really is enough for the user to know that the stash is created,
without bothering them with the internal details of what's happening.
Always pass the -q flag to the internal git clean and git reset
commands, to avoid unnecessary and potentially confusing output.

git-p4: fix multi-path changelist empty commits
When importing from multiple perforce paths - we may attempt to
import a changelist that contains files from two (or more) of these
depot paths. Currently, this results in multiple git commits - one
containing the changes, and the other(s) as empty commit(s). This
behavior was introduced in commit 1f90a64891 ("git-p4: reduce number

Reproduction Steps:
1. Have a git repo cloned from a perforce repo using multiple
depot paths (e.g. //depot/foo and //depot/bar).
2. Submit a single change to the perforce repo that makes changes
in both //depot/foo and //depot/bar.
3. Run "git p4 sync" to sync the change from #2.
Change is synced as multiple commits, one for each depot path that
was affected.
Using a set, instead of a list inside p4ChangesForPaths() ensures
that each changelist is unique to the returned list, and therefore
only a single commit is generated for each changelist.

tmp-objdir: quote paths we add to alternates
Commit 722ff7f87 (receive-pack: quarantine objects until
pre-receive accepts, 2016-10-03) regressed pushes to
repositories with colon (or semi-colon in Windows in them)
because it adds the repository's main object directory to
GIT_ALTERNATE_OBJECT_DIRECTORIES. The receiver interprets
the colon as a delimiter, not as part of the path, and
index-pack is unable to find objects which it needs to
resolve deltas.
The previous commit introduced a quoting mechanism for the
alternates list; let's use it here to cover this case. We'll
avoid quoting when we can, though. This alternate setup is
also used when calling hooks, so it's possible that the user
may call older git implementations which don't understand
the quoting mechanism. By quoting only when necessary, this
setup will continue to work unless the user _also_ has a
repository whose path contains the delimiter.

alternates: accept double-quoted paths
We read lists of alternates from objects/info/alternates
files (delimited by newline), as well as from the
GIT_ALTERNATE_OBJECT_DIRECTORIES environment variable
(delimited by colon or semi-colon, depending on the
platform).
There's no mechanism for quoting the delimiters, so it's
impossible to specify an alternate path that contains a
colon in the environment, or one that contains a newline in
a file. We've lived with that restriction for ages because
both alternates and filenames with colons are relatively
rare, and it's only a problem when the two meet. But since 722ff7f87 (receive-pack: quarantine objects until
pre-receive accepts, 2016-10-03), which builds on the
alternates system, every push causes the receiver to set
GIT_ALTERNATE_OBJECT_DIRECTORIES internally.
It would be convenient to have some way to quote the
delimiter so that we can represent arbitrary paths.
The simplest thing would be an escape character before a
quoted delimiter (e.g., "\:" as a literal colon). But that
creates a backwards compatibility problem: any path which
uses that escape character is now broken, and we've just
shifted the problem. We could choose an unlikely escape
character (e.g., something from the non-printable ASCII
range), but that's awkward to use.
Instead, let's treat names as unquoted unless they begin
with a double-quote, in which case they are interpreted via
our usual C-stylke quoting rules. This also breaks
backwards-compatibility, but in a smaller way: it only
matters if your file has a double-quote as the very _first_
character in the path (whereas an escape character is a
problem anywhere in the path). It's also consistent with
many other parts of git, which accept either a bare pathname
or a double-quoted one, and the sender can choose to quote
or not as required.

mingw: intercept isatty() to handle /dev/null as Git expects it
When Git's source code calls isatty(), it really asks whether the
respective file descriptor is connected to an interactive terminal.
Windows' _isatty() function, however, determines whether the file
descriptor is associated with a character device. And NUL, Windows'
equivalent of /dev/null, is a character device.
Which means that for years, Git mistakenly detected an associated
interactive terminal when being run through the test suite, which
almost always redirects stdin, stdout and stderr to /dev/null.
This bug only became obvious, and painfully so, when the new
bisect--helper entered the `pu` branch and made the automatic build & test
time out because t6030 was waiting for an answer.
What was intended was perhaps "... plumbing does for you" ("you" added), but
simply omitting the word "for" is more terse and gets the intended point across
just as well, if not more so.
I originally went with the approach of writing "for you", but Junio C
Hamano suggested this approach instead.

Adding the word "just" makes it clear that the point is to *not* do an
octopus merge simply because you *can* do it. In other words, you
should have a reason for doing it beyond simply having two (seemingly)
independent commits that you need to merge into another branch, since
it's not always the best approach.
The previous sentence made it look more like it was trying to say that
you shouldn't do an octopus merge *because* you can do an octopus merge.

In contrast to "git am --abort", a sequencer abort did not check

This behavior is now changed by mimicking "git am --abort". The

A new file "sequencer/abort-safety" is added to save the expected

diff: handle --no-abbrev in no-index case
There are two different places where the --no-abbrev option is parsed,
and two different places where SHA-1s are abbreviated. We normally parse
--no-abbrev with setup_revisions(), but in the no-index case, "git diff"
calls diff_opt_parse() directly, and diff_opt_parse() didn't handle
--no-abbrev until now. (It did handle --abbrev, however.) We normally
abbreviate SHA-1s with find_unique_abbrev(), but commit 4f03666 ("diff:
handle sha1 abbreviations outside of repository, 2016-10-20) recently
introduced a special case when you run "git diff" outside of a
repository.
setup_revisions() does also call diff_opt_parse(), but not for --abbrev
or --no-abbrev, which it handles itself. setup_revisions() sets
rev_info->abbrev, and later copies that to diff_options->abbrev. It
handles --no-abbrev by setting abbrev to zero. (This change doesn't
touch that.)
Setting abbrev to zero was broken in the outside-of-a-repository special
case, which until now resulted in a truly zero-length SHA-1, rather than
taking zero to mean do not abbreviate. The only way to trigger this bug,
however, was by running "git diff --raw" without either the --abbrev or
--no-abbrev options, because 1) without --raw it doesn't respect abbrev
(which is bizarre, but has been that way forever), 2) we silently clamp
--abbrev=0 to MINIMUM_ABBREV, and 3) --no-abbrev wasn't handled until
now.
The outside-of-a-repository case is one of three no-index cases. The
other two are when one of the files you're comparing is outside of the
repository you're in, and the --no-index option.

Some context before we talk about the removed code.
This paint_down() is part of step 6 of 58babff (shallow.c: the 8 steps
to select new commits for .git/shallow - 2013-12-05). When we fetch from
a shallow repository, we need to know if one of the new/updated refs
needs new "shallow commits" in .git/shallow (because we don't have
enough history of those refs) and which one.
The question at step 6 is, what (new) shallow commits are required in
other to maintain reachability throughout the repository _without_
cutting our history short? To answer, we mark all commits reachable from
existing refs with UNINTERESTING ("rev-list --not --all"), mark shallow
commits with BOTTOM, then for each new/updated refs, walk through the
commit graph until we either hit UNINTERESTING or BOTTOM, marking the
ref on the commit as we walk.
After all the walking is done, we check the new shallow commits. If we
have not seen any new ref marked on a new shallow commit, we know all
new/updated refs are reachable using just our history and .git/shallow.
The shallow commit in question is not needed and can be thrown away.
So, the code.
The loop here (to walk through commits) is basically
1. get one commit from the queue
2. ignore if it's SEEN or UNINTERESTING
3. mark it
4. go through all the parents and..
5a. mark it if it's never marked before
5b. put it back in the queue
What we do in this patch is drop step 5a because it is not
necessary. The commit being marked at 5a is put back on the queue, and
will be marked at step 3 at the next iteration. The only case it will
not be marked is when the commit is already marked UNINTERESTING (5a
does not check this), which will be ignored at step 2.
But we don't care about refs marking on UNINTERESTING. We care about the
marking on _shallow commits_ that are not reachable from our current
history (and having UNINTERESTING on it means it's reachable). So it's
ok for an UNINTERESTING not to be ref-marked.
