Commit e12a7ef597 ("rebase -i: Handle "combination of <n> commits" with
GETTEXT_POISON", 2018-04-27) changed the way that individual commit
messages are labelled when squashing commits together. In doing so a
regression was introduced where the numbering of the messages is off by
one. This commit fixes that and adds a test for the numbering.

During a series of fixup/squash commands, the interactive rebase builds
up a commit message with comments. This will be presented to the user in
the editor if at least one of those commands was a `squash`.
In any case, the commit message will be cleaned up eventually, removing
all those intermediate comments, in the final step of such a
fixup/squash chain.
However, if the last fixup/squash command in such a chain fails with
merge conflicts, and if the user then decides to skip it (or resolve it
to a clean worktree and then continue the rebase), the current code
fails to clean up the commit message.
This commit fixes that behavior.
The fix is quite a bit more involved than meets the eye because it is
not only about the question whether we are `git rebase --skip`ing a
fixup or squash. It is also about removing the skipped fixup/squash's
commit message from the accumulated commit message. And it is also about
the question whether we should let the user edit the final commit
message or not ("Was there a squash in the chain *that was not
skipped*?").
For example, in this case we will want to fix the commit message, but
not open it in an editor:
pick <- succeeds
fixup <- succeeds
squash <- fails, will be skipped
This is where the newly-introduced `current-fixups` file comes in real
handy. A quick look and we can determine whether there was a non-skipped
squash. We only need to make sure to keep it up to date with respect to
skipped fixup/squash commands. As a bonus, we can even avoid committing
unnecessarily, e.g. when there was only one fixup, and it failed, and
was skipped.
To fix only the bug where the final commit message was not cleaned up
properly, but without fixing the rest, would have been more complicated
than fixing it all in one go, hence this commit lumps together more than
a single concern.
For the same reason, this commit also adds a bit more to the existing
test case for the regression we just fixed.
The diff is best viewed with --color-moved.

Previously, we only called run_git_commit() without EDIT_MSG when we also
passed in a default message.
However, an upcoming caller will want to commit without EDIT_MSG and
*without* a default message: to clean up fixup/squash comments in HEAD's
commit message.
Let's prepare for that.

We previously relied on the localized versions of
# This is a combination of <N> commits
(which we write into the commit messages during fixup/squash chains)
to contain <N> encoded in ASCII.
This is not true in general, and certainly not true when compiled with
GETTEXT_POISON=TryToKillMe, as demonstrated by the regression test we
just introduced in t3418.
So let's decouple keeping track of the count from the (localized) commit
messages by introducing a new file called 'current-fixups' that keeps
track of the current fixup/squash chain. This file contains a bit more
than just the count (it contains a list of "fixup <commit>"/"squash
<commit>" lines). This is done on purpose, as it will come in handy for
a fix for the bug where `git rebase --skip` on a final fixup/squash will
leave the commit message in limbo.

When multiple fixup/squash commands are processed and the last one
causes merge conflicts and is skipped, we leave the "This is a
combination of ..." comments in the commit message.
Noticed by Eric Sunshine.
This regression test also demonstrates that we rely on the localized
version of
# This is a combination of <number> commits
to contain the <number> in ASCII, which breaks under GETTEXT_POISON.

Fix a regression in 88f6ffc1c2 ("add -p: only bind search key if
there's more than one hunk", 2018-02-13) which is present in
2.17.0-rc*, but not 2.16.0.
In Perl, regex variables like $1 always refer to the last regex
match. When the aforementioned change added a new regex match between
the old match and the corresponding code that was expecting $1, the $1
variable would always be undef, since the newly inserted regex match
doesn't have any captures.
As a result the "/" feature to search for a string in a hunk by regex
completely broke, on git.git:
$ perl -pi -e 's/Git/Tig/g' README.md
$ ./git --exec-path=$PWD add -p
[..]
Stage this hunk [y,n,q,a,d,j,J,g,/,s,e,?]? s
Split into 4 hunks.
[...]
Stage this hunk [y,n,q,a,d,j,J,g,/,s,e,?]? /Many
Use of uninitialized value $1 in string eq at /home/avar/g/git/git-add--interactive line 1568, <STDIN> line 1.
search for regex? Many
I.e. the initial "/regex" command wouldn't work, and would always emit
a warning and ask again for a regex, now it works as intended again.

When upload-pack gained partial clone support (v2.17.0-rc0~132^2~12,
2017-12-08), it was guarded by the uploadpack.allowFilter config item
to allow server operators to control when they start supporting it.
That config item didn't go far enough, though: it controls whether the
'filter' capability is advertised, but if a (custom) client ignores
the capability advertisement and passes a filter specification anyway,
the server would handle that despite allowFilter being false.
This is particularly significant if a security bug is discovered in
this new experimental partial clone code. Installations without
uploadpack.allowFilter ought not to be affected since they don't
intend to support partial clone, but they would be swept up into being
vulnerable.
Simplify and limit the attack surface by making uploadpack.allowFilter
disable the feature, not just the advertisement of it.

Hotfix for recently graduated topic that give help to completion
scripts from the Git subcommands that are being completed
* nd/parseopt-completion:
t9902: disable test on the list of merge-strategies under GETTEXT_POISON
completion: clear cached --options when sourcing the completion script
This fixes a regression introduced in 2e612731b5 (submodule: port
submodule subcommand 'deinit' from shell to C, 2018-01-15), when
handling pathspecs that do not exist gracefully. This restores the
historic behavior of reporting the pathspec as unknown and returning
instead of reporting a bug.

In 1ada5020b3 ("stash: use stash_push for no verb form", 2017-02-28),
when the pathspec argument was introduced in 'git stash', that was also
documented. However I forgot to remove an extra square bracket after
the '--message' argument, even though the square bracket should have
been after the pathspec argument (where it was also added).
Remove the extra square bracket after the '--message' argument, to show
that the pathspec argument should be used with the 'push' verb.
While the pathspec argument can be used without the push verb, that's a
special case described later in the man page, and removing the first extra
square bracket instead of the second one makes the synopis easier to
understand.

The code to learn the list of merge strategies from the output of
"git merge -s help" forces C locale, so that it can notice the
message shown to indicate where the list starts in the output.
However, GETTEXT_POISON build corrupts its output even when run in
the C locale, and we cannot expect this test to succeed.
