The final step to make an empty string as a pathspec element
illegal. We started this by first deprecating and warning a
pathspec that has such an element in 2.11 (Nov 2016).

year? A deprecation warning period that is about 1 year does not
sound too bad.

An earlier update made it possible to use an on-stack in-core
lockfile structure (as opposed to having to deliberately leak an
on-heap one). Many codepaths have been updated to take advantage
of this new facility.
* ma/lockfile-fixes:
read_cache: roll back lock in `update_index_if_able()`
read-cache: leave lock in right state in `write_locked_index()`
read-cache: drop explicit `CLOSE_LOCK`-flag
cache.h: document `write_locked_index()`
apply: remove `newfd` from `struct apply_state`
apply: move lockfile into `apply_state`
cache-tree: simplify locking logic
checkout-index: simplify locking logic
tempfile: fix documentation on `delete_tempfile()`
lockfile: fix documentation on `close_lock_file_gently()`
treewide: prefer lockfiles on the stack
sha1_file: do not leak `lock_file`
This heuristic has been the default since 2.14 so we should not confuse our
users by saying that it's experimental and off by default.

With --recurse-submodules, we add each submodule that we encounter to
the list of alternate object databases. With threading, our changes to
the list are not protected against races. Indeed, ThreadSanitizer
reports a race when we call `add_to_alternates_memory()` around the same
time that another thread is reading in the list through
`read_sha1_file()`.
Take the grep read-lock while adding the submodule. The lock is used to
serialize uses of non-thread-safe parts of Git's API, including
`read_sha1_file()`.

When we replaced the old shell script based interactive rebase in
commmit 18633e1a22 ("rebase -i: use the rebase--helper builtin",
2017-02-09) we introduced a regression of functionality in that the
GIT_DIR would be sent to the environment of the exec command as-is.
This generally meant that it would be passed as "GIT_DIR=.git", which
causes problems for any exec command that wants to run git commands in
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
need to do so in a subdir. This regression was discovered by a build
system which uses git-describe to find the current version of the build
system, and happened to do so from the src/ sub directory of the
project.
Fix this by passing in the absolute path of the git directory into the
child environment.

With the 'git stash save' interface, it was easily possible for users to
try to add a message which would start with "-", which 'git stash save'
would interpret as a command line argument, and fail. For this case we
added some extra help on how to create a stash with a message starting
with "-".
For 'stash push', messages are passed with the -m flag, avoiding this
potential pitfall. Now only pathspecs starting with "-" would have to
be distinguished from command line parameters by using
"-- --<pathspec>". This is fairly common in the git command line
interface, and we don't try to guess what the users wanted in the other
cases.
Because this way of passing pathspecs is quite common in other git
commands, and we don't provide any extra help there, do the same in the
error message for 'git stash push'.

'git stash push' fixes a historical wart in the interface of 'git stash
save'. As 'git stash push' has all functionality of 'git stash save',
with a nicer, more consistent user interface deprecate 'git stash
save'. To do this, remove it from the synopsis of the man page, and
move it to a separate section, stating that it is deprecated.

"git stash push" is the newer interface for creating a stash. While we
are still keeping "git stash save" around for the time being, it's better
to point new users of "git stash" to the more modern (and more feature
rich) interface, instead of teaching them the older version that we
might want to phase out in the future.

We meticulously pass the `exclude` flag to the `treat_directory()`
function so that we can indicate that files in it are excluded rather
than untracked when recursing.
But we did not yet treat submodules the same way.
Because of that, `git status --ignored --untracked` with a submodule
`submodule` in a gitignored `tracked/` would show the submodule in the
"Untracked files" section, e.g.
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
tracked/submodule/
Ignored files:
(use "git add -f <file>..." to include in what will be committed)
tracked/submodule/initial.t
Instead, we would want it to show the submodule in the "Ignored files"
section:
On branch master

The implementations in diff.c to detect moved lines needs to compare
strings and hash strings, which is implemented in that file, as well
as in the xdiff library.
Remove the rather recent implementation in diff.c and rely on the well
exercised code in the xdiff lib.
With this change the hash used for bucketing the strings for the moved
line detection changes from FNV32 (that is provided via the hashmaps
memhash) to DJB2 (which is used internally in xdiff). Benchmarks found
on the web[1] do not indicate that these hashes are different in
performance for readable strings.
