When a user does not tell "git pull" to use rebase or merge, the
command gives a loud message telling a user to choose between
rebase or merge but creates a merge anyway, forcing users who would
want to rebase to redo the operation. Fix an early part of this
problem by tightening the condition to give the message---there is
no reason to stop or force the user to choose between rebase or
merge if the history fast-forwards.

"Keep it homogeneous across the repository" is in general a
guideline that can be used to converge to a good practice, but
we can be a bit more prescriptive in this case. Just like the
messages we give die(_("...")) are formatted without the final
full stop and without the initial capitalization, most of the
argument help text are already formatted that way, and we want
to encourage that as the house style.

p7519 measures the performance of the fsmonitor code. To do this, it
uses the installed copy of Watchman. If Watchman isn't installed, a noop
integration script is installed in its place.
When in the latter mode, it is expected that the script should not write
a "last update token": in fact, it doesn't write anything at all since
the script is blank.
Commit 33226af42b (t/perf/fsmonitor: improve error message if typoing
hook name, 2020-10-26) made sure that running 'git update-index
--fsmonitor' did not write anything to stderr, but this is not the case
when using the empty Watchman script, since Git will complain that:
$ which watchman
watchman not found
$ cat .git/hooks/fsmonitor-empty
$ git -c core.fsmonitor=.git/hooks/fsmonitor-empty update-index --fsmonitor
warning: Empty last update token.
Prior to 33226af42b, the output wasn't checked at all, which allowed
this noop mode to work. But, 33226af42b breaks p7519 when running it
without a 'watchman(1)' on your system.
Handle this by only checking that the stderr is empty only when running
with a real watchman executable. Otherwise, assert that the error
message is the expected one when running in the noop mode.

When __git_complete was introduced, it was meant to be temporarily, while
a proper guideline for public shell functions was established
(tentatively _GIT_complete), but since that never happened, people
in the wild started to use __git_complete, even though it was marked as
not public.
Eight years is more than enough wait, let's mark this function as
public, and make it a bit more user-friendly.
So that instead of doing:
__git_complete gk __gitk_main
The user can do:
__git_complete gk gitk
And instead of:
__git_complete gf _git_fetch
Do:
__git_complete gf git_fetch
Backwards compatibility is maintained.

We trace statistics about the effectiveness of changed-path Bloom
filters since 42e50e78 (revision.c: add trace2 stats around Bloom
filter usage, 2020-04-06). Add similar tracing for the topo-walk
algorithm that uses generation numbers to limit the walk size.
This information can help investigate and describe benefits to
heuristics and other changes.
The information that is printed is in JSON format and can be formatted
nicely to present as follows:
{
"count_explort_walked":2603,
"count_indegree_walked":2603,
"count_topo_walked":473
}
Each of these values count the number of commits are visited by each of
the three "stages" of the topo-walk as detailed in b4542418 (revision.c:
generation-based topo-order algorithm, 2018-11-01).

t6016 manually reconstructs git log --graph output by using the reported
commit hashes from `git rev-parse`. Each tag is converted into an
environment variable manually, and then `echo`-ed to an expected output
file, which is in turn compared to the actual output.
The expected output is difficult to read and write, because, e.g.,
each line of output must be prefaced with echo, quoted, and properly
escaped. Additionally, the test is sensitive to trailing whitespace,
which may potentially be removed from graph log output in the future.
In order to reduce duplication, ease troubleshooting of failed tests by
improving readability, and ease the addition of more tests to this file,
port the operations to `lib-log-graph.sh`, which is already used in
several other tests, e.g., t4215. Give all merges a simple commit
message, and use a common `check_graph` macro taking a heredoc of the
expected output which does not required extensive escaping.

We use various made-up config keys in the "core" section for no real
reason. Change them to work in the "section" section instead and be
careful to also change "cores" to "sections". Make sure to also catch
"Core", "CoReS" and similar.
There are a few instances that actually want to work with a real "core"
config such as `core.bare` or `core.editor`. After this, it's clearer
that they work with "core" for a reason.

We test that we can handle `git config --file symlink` and the error
case of `git config --file symlink-to-missing-file`. For good measure,
we also throw in a test to check that we correctly handle referencing a
missing regular file. But we have such a test earlier in this script.
They both check that we fail to use `--file no-such-file --list`.
Drop the latter of these and keep the one that is in the general area
where we test `--file` and `GIT_CONFIG`. The one we're dropping also
checks that we can't even get a specific key from the missing file --
let's make sure we check that in the test we keep.

We have two tests for checking that we can handle `git config --file
../other-config ...`. One, using `--file`, was introduced in 65807ee697
("builtin-config: Fix crash when using "-f <relative path>" from
non-root dir", 2010-01-26), then another, using `GIT_CONFIG`, came about
in 270a34438b ("config: stop using config_exclusive_filename",
2012-02-16).
The latter of these was then converted to use `--file` in f7e8714101
("t: prefer "git config --file" to GIT_CONFIG", 2014-03-20). Both where
then simplified in a5db0b77b9 ("t1300: extract and use
test_cmp_config()", 2018-10-21).
These two tests differ slightly in the order of the options used, but
other than that, they are identical. Let's drop one. As noted in
f7e8714101, we do still have a test for `GIT_CONFIG` and it shares the
implementation with `--file`.

'gitmodules.txt' is a guide about the '.gitmodules' file that describes

repository. This was clarified in e5b5c1d2cf (Document clarification:
gitmodules, gitattributes, 2008-08-31).
However, that commit mistakenly uses the non-existing environment
variable 'GIT_WORK_DIR' to refer to the root of the repository.
Fix that by using the correct variable, 'GIT_WORK_TREE'. Take the
opportunity to modernize and improve the formatting of that guide,
and fix a grammar mistake.
