Analogous to commit, introduce a '--no-verify' option which bypasses the
pre-merge-commit hook. The shorthand '-n' is taken by '--no-stat'
already.
[js: * reworded commit message to reflect current state of --no-stat flag
and new hook name
* fixed flag documentation to reflect new hook name
* cleaned up trailing whitespace
* squashed test changes from the original series' patch 4/4
* modified tests to follow pattern from this series' patch 1/4
* added a test case for --no-verify with non-executable hook
* when testing that the merge hook did not run, make sure we
actually have a merge to perform (by resetting the "side" branch
to its original state).

git-merge does not honor the pre-commit hook when doing automatic merge
commits, and for compatibility reasons this is going to stay.
Introduce a pre-merge-commit hook which is called for an automatic merge
commit just like pre-commit is called for a non-automatic merge commit
(or any other commit).
[js: * renamed hook from "pre-merge" to "pre-merge-commit"
* only discard the index if the hook is actually present
* expanded githooks documentation entry
* clarified that hook should write messages to stderr
* squashed test changes from the original series' patch 4/4
* modified tests to follow new pattern from this series' patch 1/4
* added a test case for non-executable merge hooks
* added a test case for failed merges
* when testing that the merge hook did not run, make sure we
actually have a merge to perform (by resetting the "side" branch
to its original state).
* reworded commit message

t7503 did not verify that the expected hooks actually ran during
testing. Fix that by making the hook scripts write their $0 into a file
so that we can compare actual execution vs. expected execution.
While we're at it, do some test style cleanups, such as using
write_script() and doing setup inside a test_expect_success block.

It turns out that being cautious to warn against upcoming default

Since 07b2c0eacac (config: learn the "onbranch:" includeIf condition,
2019-06-05), there is a potential catch-22 in the early config path: if
the `include.onbranch:` feature is used, Git assumes that the Git
directory has been initialized already. However, in the early config
code path that is not true.
One way to trigger this is to call the following commands in any
repository:
git config includeif.onbranch:refs/heads/master.path broken
git help -a
The symptom triggered by the `git help -a` invocation reads like this:
BUG: refs.c:1851: attempting to get main_ref_store outside of repository
Let's work around this, simply by ignoring the `includeif.onbranch:`
setting when parsing the config when the ref store has not been
initialized (yet).
Technically, there is a way to solve this properly: teach the refs
machinery to initialize the ref_store from a given gitdir/commondir pair
(which we _do_ have in the early config code path), and then use that in
`include_by_branch()`. This, however, is a pretty involved project, and
we're already in the feature freeze for Git v2.23.0.
Note: when calling above-mentioned two commands _outside_ of any Git
worktree (passing the `--global` flag to `git config`, as there is
obviously no repository config available), at the point when
`include_by_branch()` is called, `the_repository` is `NULL`, therefore
we have to be extra careful not to dereference it in that case.

Commit 7328482253 (repack: disable bitmaps-by-default if .keep files
exist, 2019-06-29) taught repack to prefer disabling bitmaps to
duplicating objects (unless bitmaps were asked for explicitly).
But there's an easier way to do this: if we keep passing the
--honor-pack-keep flag to pack-objects when auto-enabling bitmaps, then
pack-objects already makes the same decision (it will disable bitmaps
rather than duplicate). Better still, pack-objects can actually decide
to do so based not just on the presence of a .keep file, but on whether
that .keep file actually impacts the new pack we're making (so if we're
racing with a push or fetch, for example, their temporary .keep file
will not block us from generating bitmaps if they haven't yet updated
their refs).
And because repack uses the --write-bitmap-index-quiet flag, we don't
have to worry about pack-objects generating confusing warnings when it
does see a .keep file. We can confirm this by tweaking the .keep test to
check repack's stderr.

Depending on various config options, a full repack may not be able to
build a reachability bitmap index (e.g., if pack.packSizeLimit forces us
to write multiple packs). In these cases pack-objects may write a
warning to stderr.
Since 36eba0323d (repack: enable bitmaps by default on bare repos,
2019-03-14), we may generate these warnings even when the user did not
explicitly ask for bitmaps. This has two downsides:
- it can be confusing, if they don't know what bitmaps are
- a daemonized auto-gc will write this to its log file, and the
presence of the warning may suppress further auto-gc (until
gc.logExpiry has elapsed)
Let's have repack communicate to pack-objects that the choice to turn on
bitmaps was not made explicitly by the user, which in turn allows
pack-objects to suppress these warnings.

The iteration order of a hashmap is undefined, and may depend on things
like the exact set of items added, or the table has been grown or
shrunk. In the case of an oidmap, it even depends on endianness, because
we take the oid hash by casting sha1 bytes directly into an unsigned
int.
Let's sort the test-tool output from any hash iterators. In the case of
t0011, this is just future-proofing. But for t0016, it actually fixes a
reported failure on the big-endian s390 and nonstop ports.
I didn't bother to teach the helper functions to optionally sort output.
They are short enough that it's simpler to just repeat them inline for
the iteration tests than it is to add a --sort option.

A few tests printed 'errno' as an integer and compared with
hardcoded integers; this is obviously not portable.
A two things to note are:
- the string obtained by strerror() is not portable, and cannot be
used for the purpose of these tests.
- there unfortunately isn't a portable way to map error numbers to
error names.
As we only care about a few selected errors, just map the error
number to the name before emitting for comparison.

After finding a function line for --function-context in the pre-image,
xdl_emit_diff() calculates the equivalent line in the post-image. It
assumes that the lines between changes are the same on both sides. If
the option --ignore-blank-lines was also given then this is not
necessarily true.
Clamp the calculation results for start and end of the function context
to prevent out-of-bounds array accesses.
Note that this _just_ fixes the case where our mismatch sends us off the
beginning of the file. There are likely other cases where our assumption
causes us to go to the wrong line within the file. Nobody has developed
a test case yet, and the ultimate fix is likely more complicated than
this patch. But this at least prevents a segfault in the meantime.
Credit for finding the bug goes to "Liu Wei of Tencent Security Xuanwu
Lab".

When `lstat()` failed, `git clean` would abort without an error
message, leaving the user quite puzzled.
In particular on Windows, where the default maximum path length is
quite small (yet there are ways to circumvent that limit in many
cases), it is very important that users be given an indication why
their command failed because of too long paths when it did.
This test case makes sure that a warning is issued that would have
helped the user who reported this issue:
https://github.com/git-for-windows/git/issues/521
Note that we temporarily set `core.longpaths = false` in the regression
test; this ensures forward-compatibility with the `core.longpaths`
feature that has not yet been upstreamed from Git for Windows.

When resolving a conflict on a path in favor of removing it, using
"git rm" on it is the standard way to do so. The user however is
greeted with a "needs merge" message during that operation:
$ git merge side-branch
$ edit conflicted-path-1
$ git add conflicted-path-1
$ git rm conflicted-path-2
conflicted-path-2: needs merge
rm 'conflicted-path-2'
The removal by "git rm" does get performed, but an uninitiated user
may find it confusing, "needs merge? so I need to resolve conflict
before being able to remove it???"
The message is coming from "update-index --refresh" that is called
internally to make sure "git rm" knows which paths are clean and
which paths are dirty, in order to prevent removal of paths modified
relative to the index without the "-f" option. We somehow ended up
not squelching this message which seeped through to the UI surface.
Use the same mechanism used by "git commit", "git describe", etc. to
squelch the message.

git stash push --keep-index is supposed to keep all changes that have
been added to the index, both in the index and on disk.
Currently this doesn't behave correctly when a file is removed from
the index. Instead of keeping it deleted on disk, --keep-index
currently restores the file.
Fix that behaviour by using 'git checkout' in no-overlay mode which
can faithfully restore the index and working tree. This also
simplifies the code.
Note that this will overwrite untracked files if the untracked file
has the same name as a file that has been deleted in the index.

On some older Windows versions (e.g. Windows 7), the CreateProcessW()
function does not really support spaces in its first argument,
lpApplicationName. But it supports passing NULL as lpApplicationName,
which makes it figure out the application from the (possibly quoted)
first argument of lpCommandLine.
Let's use that trick (if we are certain that the first argument matches
the executable's path) to support launching programs whose path contains
spaces.
We will abuse the test-fake-ssh.exe helper to verify that this works and
does not regress.

Teach transport-helper how to notice if skipping a ref during push would
violate atomicity on the client side. We notice that a ref would be
rejected, and choose not to send it, but don't notice that if the client
has asked for --atomic we are violating atomicity if all the other
pushes we are sending would succeed. Asking the server end to uphold
atomicity wouldn't work here as the server doesn't have any idea that we
tried to update a ref that's broken.
The added test-case is a succinct way to reproduce this issue that fails
today. The same steps work fine when we aren't using a transport-helper
to get to the upstream, i.e. when we've added a local repository as a
remote:
git remote add ~/upstream upstream
