The prompt_yesno function loops indefinitely waiting for a
"y" or "n" response. But it doesn't handle EOF, meaning
that we can end up in an infinite loop of reading EOF from
stdin. One way to simulate that is with:
echo e | GIT_EDITOR='echo corrupt >' git add -p
Let's break out of the loop and propagate the undef to the
caller. Without modifying the callers that effectively turns
it into a "no" response. This is reasonable for both of the
current callers, and it leaves room for any future caller to
check for undef explicitly.

Fix an erroneously copy/pasted check for the pcre2_jit_stack variable
to check pcre2_match_context instead. The former was already checked
in the preceding "if" statement.
This is a trivial and obvious error introduced in my commit
94da9193a6 ("grep: add support for PCRE v2", 2017-06-01).
In practice if pcre2_match_context_create() returned NULL we were
likely in a situation where malloc() was returning NULL, and were thus
screwed anyway, but if only the pcre2_match_context_create() call
returned NULL (through some transitory bug) PCRE v2 would just
allocate and supply its own context object when matching, and we'd run
normally at the trivial expense of not getting a slight speedup by
sharing the context object between successive matches.

`for_each_bisect_ref()` is called by `for_each_bad_bisect_ref()` with

macro in xdiff/xmacros.h added in commit 3443546f6e ("Use a *real*

free() is called unconditionally, see [1].
See [2] for a suggested alternative which does this via a function
instead of a macro. As covered in replies to that message, while it's
a viable approach, it would introduce caveats which this approach
doesn't have, so that potential change is left to a future follow-up
change.
This merely allows us to translate exactly what we're doing now to a
less verbose & idiomatic form using a macro, while guaranteeing that
we don't introduce any functional changes.

When we convert seconds-since-epochs timestamps into a
broken-down "struct tm", we do so by adjusting the timestamp
according to the known offset and then using gmtime() to
break down the result. This means that the resulting struct
"knows" that it's in GMT, even though the time it represents
is adjusted for a different zone. The fields where it stores
this data are not portably accessible, so we have no way to
override them to tell them the real zone info.
For the most part, this works. Our date-formatting routines
don't pay attention to these inaccessible fields, and use
the same tz info we provided for adjustment. The one
exception is when we call strftime(), whose %Z format
reveals this hidden timezone data.
We solved that by always showing the empty string for %Z.
This is allowed by POSIX, but not very helpful to the user.
We can't make this work in the general case, as there's no
portable function for setting an arbitrary timezone (and
anyway, we don't have the zone name for the author zones,
only their offsets).
But for the special case of the "-local" formats, we can
just skip the adjustment and use localtime() instead of
gmtime(). This makes --date=format-local:%Z work correctly,
showing the local timezone instead of an empty string.
The new test checks the result for "UTC", our default
test-lib value for $TZ. Using something like EST5 might be
more interesting, but the actual zone string is
system-dependent (for instance, on my system it expands to
just EST). Hopefully "UTC" is vanilla enough that every
system treats it the same.

We already test that "%z" and "%Z" show the right thing, but
we don't actually check that the time we display is the
correct one. Let's add two new tests:
1. Test that "format:" shows the time in the author's
timezone, just like the other time formats.
2. Test that "format-local:" shows time in the local
timezone. We don't want to use our normal UTC for this,
because its offset is zero (so the result would be
"correct" even if the code forgot to apply the offset
or applied it in the wrong direction).
We'll use the EST5 zone, which is already used
elsewhere in the script (and so is assumed to be
available everywhere).

There is no portable way to pass timezone information to strftime. Add
parameters for timezone offset and name to strbuf_addftime and let it
handle the timezone-related format specifiers %z and %Z internally.
Callers can opt out for %Z by passing NULL as timezone name. %z is
always handled internally -- this helps on Windows, where strftime would
expand it to a timezone name (same as %Z), in violation of POSIX.
Modifiers are not handled, e.g. %Ez is still passed to strftime.
Use an empty string as timezone name in show_date (the only current
caller) for now because we only have the timezone offset in non-local
mode. POSIX allows %Z to resolve to an empty string in case of missing
information.

We added an FREAD_READS_DIRECTORIES Makefile knob long ago
in cba22528f (Add compat/fopen.c which returns NULL on
attempt to open directory, 2008-02-08) to handle systems
where reading from a directory returned garbage. This works
by catching the problem at the fopen() stage and returning
NULL.
More recently, we found that there is a class of systems
(including Linux) where fopen() succeeds but fread() fails.
Since the solution is the same (having fopen return NULL),
they use the same Makefile knob as of e2d90fd1c
(config.mak.uname: set FREAD_READS_DIRECTORIES for Linux and
FreeBSD, 2017-05-03).
This works fine except for one thing: the autoconf test in
configure.ac to set FREAD_READS_DIRECTORIES actually checks
whether fread succeeds. Which means that on Linux systems,
the knob isn't set (and we even override the config.mak.uname
default). t1308 catches the failure.
We can fix this by tweaking the autoconf test to cover both
cases. In theory we might care about the distinction between
the traditional "fread reads directories" case and the new
"fopen opens directories". But since our solution catches
the problem at the fopen stage either way, we don't actually
need to know the difference. The "fopen" case is a superset.
This does mean the FREAD_READS_DIRECTORIES name is slightly
misleading. Probably FOPEN_OPENS_DIRECTORIES would be more
accurate. But it would be disruptive to simply change the
name (people's existing build configs would fail), and it's
not worth the complexity of handling both. Let's just add a
comment in the knob description.

Worktrees present an interesting problem when it comes to the config.
Historically we could assume that the per-repository config lives at
'gitdir/config', but since worktrees were introduced this isn't the case
anymore. There is currently no way to specify per-worktree
configuration, and as such the repository config is shared with all
worktrees and is located at 'commondir/config'.
Many users of the config machinery correctly set
'config_options.git_dir' with the repository's commondir, allowing the
config to be properly loaded when operating in a worktree. But other's,
like 'read_early_config()', set 'config_options.git_dir' with the
repository's gitdir which can be incorrect when using worktrees.
To fix this issue, and to make things less ambiguous, lets add a
'commondir' field to the 'config_options' struct and have all callers
properly set both the 'git_dir' and 'commondir' fields so that the
config machinery is able to properly find the repository's config.

repository config, which is checked to verify the repository's format,

this behavior by checking the config stored in the commondir.

Instead of discovering the .git/ directory, reading the config and then

It may look like unnecessary work to discover the .git/ directory in the
early config machinery and then call setup_git_directory_gently() in the
case of a shell alias, repeating the very same discovery *again*.
However, we have to do this as the early config machinery takes pains
*not* to touch any global state, while shell aliases expect a possibly
changed working directory and at least the GIT_PREFIX and GIT_DIR
variables to be set.

Git has this feature which suggests similar commands (including aliases)
in case the user specified an unknown command.
This feature currently relies on a side effect of the way we expand
aliases right now: when a command is not a builtin, we use the regular
config machinery (meaning: discovering the .git/ directory and
initializing global state such as the config cache) to see whether the
command refers to an alias.
However, we will change the way aliases are expanded in the next
commits, to use the early config instead. That means that the
autocorrect feature can no longer discover the available aliases by
looking at the config cache (because it has not yet been initialized).
So let's just use the early config machinery instead.
This is slightly less performant than the previous way, as the early
config is used *twice*: once to see whether the command refers to an
alias, and then to see what aliases are most similar. However, this is
hardly a performance-critical code path, so performance is less important
here.

However, when git_parse_source() asks get_value() to parse the key/value
