Completion for "git checkout <branch>" that auto-creates the branch
out of a remote tracking branch can now be disabled, as this
completion often gets in the way when completing to checkout an
existing local branch that happens to share the same prefix with
bunch of remote tracking branches.

The building of the reflog message is using strbuf, which is not

messages are translated right now and switching all the messages to
i18n would require a major rework of the way the messages are built.

githooks.txt: clarify push hooks are always executed in $GIT_DIR
Listing the specific hooks might feel verbose but without it the
reader is left to wonder which hooks are triggered during the
push. Something which is not immediately obvious when only trying
to find out where the hook is executed.

rebase -i: reread the todo list if `exec` touched it
In the scripted version of the interactive rebase, there was no internal
representation of the todo list; it was re-read before every command.
That allowed the hack that an `exec` command could append (or even
completely rewrite) the todo list.
This hack was broken by the partial conversion of the interactive rebase
to C, and this patch reinstates it.
We also add a small test to verify that this fix does not regress in the
future.

prio_queue_reverse: don't swap elements with themselves
Our array-reverse algorithm does the usual "walk from both
ends, swapping elements". We can quit when the two indices
are equal, since:
1. Swapping an element with itself is a noop.
2. If i and j are equal, then in the next iteration i is
guaranteed to be bigge than j, and we will exit the
loop.
So exiting the loop on equality is slightly more efficient.
And more importantly, the new SWAP() macro does not expect
to handle noop swaps; it will call memcpy() with the same src
and dst pointers in this case. It's unclear whether that
causes a problem on any platforms by violating the
"overlapping memory" constraint of memcpy, but it does cause
valgrind to complain.

When we complete branch names for "git checkout", we also
complete remote branch names that could trigger the DWIM
behavior. Depending on your workflow and project, this can
be either convenient or annoying.
For instance, my clone of gitster.git contains 74 local
"jk/*" branches, but origin contains another 147. When I
want to checkout a local branch but can't quite remember the
name, tab completion shows me 251 entries. And worse, for a
topic that has been picked up for pu, the upstream branch
name is likely to be similar to mine, leading to a high
probability that I pick the wrong one and accidentally
create a new branch.
This patch adds a way for the user to tell the completion
code not to include DWIM suggestions for checkout. This can
already be done by typing:
git checkout --no-guess jk/<TAB>
but that's rather cumbersome. The downside, of course, is
that you no longer get completion support when you _do_ want
to invoke the DWIM behavior. But depending on your workflow,
that may not be a big loss (for instance, in git.git I am
much more likely to want to detach, so I'd type "git
checkout origin/jk/<TAB>" anyway).

completion: expand "push --delete <remote> <ref>" for refs on that <remote>
Change the completion of "push --delete <remote> <ref>" to complete
refs on that <remote>, not all refs.
Before this cloning git.git and doing "git push --delete origin
p<TAB>" will complete nothing, since a fresh clone of git.git will
have no "pu" branch, whereas origin/p<TAB> will uselessly complete
origin/pu, but fully qualified references aren't accepted by
"--delete".
Now p<TAB> will complete as "pu". The completion of giving --delete
later, e.g. "git push origin --delete p<TAB>" remains unchanged, this
is a bug, but is a general existing limitation of the bash completion,
and not how git-push is documented, so I'm not fixing that case, but
adding a failing TODO test for it.

The only caller of this function passes in a static buffer
returned from git_path(). This looks dangerous at first
glance, but turns out to be OK because the first thing we do
is xstrdup() the result.
Let's turn this into a git_pathdup(). That's slightly more
efficient (no extra copy), and makes it easier to audit for
dangerous git_path() invocations.
Since there's only a single caller, let's just set this
default path inside the init function. That makes the memory
ownership clear.

read-cache: avoid using git_path() in freshen_shared_index()
When performing an interactive rebase in split-index mode,
the commit message that one should rework when squashing commits
can contain some garbage instead of the usual concatenation of
both of the commit messages.
The code uses git_path() to compute the shared index filename, and
passes it to check_and_freshen_file() as its argument; there is no
guarantee that the rotating pathname buffer passed as argument will
stay valid during the life of this call. Make our own copy before
calling the function and pass the copy as its argument to avoid this
risky pattern.

As explained in the document. This option has an advantage over the
command sequence "git worktree add && git worktree lock": there will be
no gap that somebody can accidentally "prune" the new worktree (or soon,
explicitly "worktree remove" it).
"worktree add" does keep a lock on while it's preparing the worktree.
If --lock is specified, this lock remains after the worktree is created.
