bbfbcd25b3 test-lib: have --immediate emit valid TAP on failure
Change the "--immediate" option so that it emits valid TAP on
failure. Before this it would omit the required plan at the end,
e.g. under SANITIZE=leak we'd show a "No plan found in TAP output"
error from "prove":

    $ prove t0006-date.sh ::  --immediate
    t0006-date.sh .. Dubious, test returned 1 (wstat 256, 0x100)
    Failed 1/22 subtests

Now we'll emit output that doesn't result in TAP parsing failures:

    $ prove t0006-date.sh ::  --immediate
    t0006-date.sh .. Dubious, test returned 1 (wstat 256, 0x100)

5891c76cd0 reset: show --no-refresh in the short-help
In the short help output from "git reset -h", the recently added
"--[no-]refresh" option is shown like so:

        --refresh             skip refreshing the index after reset

which explains what happens when the option is given in the negative
form, i.e. "--no-refresh".  We could rephrase the explanation to
read "refresh the index after reset (default)" to hint that the user
can say "--no-refresh" to override the default, but listing the
"--no-refresh" form in the list of options would be more helpful.

7cff6765fe reset: remove 'reset.refresh' config option
Remove the 'reset.refresh' option, requiring that users explicitly specify
'--no-refresh' if they want to skip refreshing the index.

The 'reset.refresh' option was introduced in 101cee42dd (reset: introduce
--[no-]refresh option to --mixed, 2022-03-11) as a replacement for the
refresh-skipping behavior originally controlled by 'reset.quiet'.

Although 'reset.refresh=false' functionally served the same purpose as
'reset.quiet=true', it exposed [1] the fact that the existence of a global
"skip refresh" option could potentially cause problems for users. Allowing a
global config option to avoid refreshing the index forces scripts using 'git
reset --mixed' to defensively use '--refresh' if index refresh is expected;
if that option is missing, behavior of a script could vary from user-to-user
without explanation.

Furthermore, globally disabling index refresh in 'reset --mixed' was
initially devised as a passive performance improvement; since the
introduction of the option, other changes have been made to Git (e.g., the
sparse index) with a greater potential performance impact without
sacrificing index correctness. Therefore, we can more aggressively err on
the side of correctness and limit the cases of skipping index refresh to
only when a user specifies the '--no-refresh' option.

2efc9b84e5 reset: remove 'reset.quiet' config option
Remove the 'reset.quiet' config option, remove '--no-quiet' documentation in
'Documentation/git-reset.txt'. In 4c3abd0551 (reset: add new reset.quiet
config setting, 2018-10-23), 'reset.quiet' was introduced as a way to
globally change the default behavior of 'git reset --mixed' to skip index
refresh.

However, now that '--quiet' does not affect index refresh, 'reset.quiet'
would only serve to globally silence logging. This was not the original
intention of the config setting, and there's no precedent for such a setting
in other commands with a '--quiet' option, so it appears to be obsolete.

In addition to the options & its documentation, remove 'reset.quiet' from
the recommended config for 'scalar'.

45bf76284b reset: do not make '--quiet' disable index refresh
Update '--quiet' to no longer implicitly skip refreshing the index in a
mixed reset. Users now have the ability to explicitly disable refreshing the
index with the '--no-refresh' option, so they no longer need to use
'--quiet' to do so. Moreover, we explicitly remove the refresh-skipping
behavior from '--quiet' because it is completely unrelated to the stated
purpose of the option: "Be quiet, only report errors."

Commit 6d158cba28 (bash completion: Support "divergence from upstream"
messages in __git_ps1, 2010-06-17) introduced support for indicating
divergence from upstream in the PS1 prompt. The comments at the top of
git-prompt.sh that were introduced with that commit are several
paragraphs long. Over the years, other comments have been inserted in
between the paragraphs relating to divergence from upstream.

This commit puts the comments relating to divergence from upstream back
together.

51d2d67790 git-prompt: make long upstream state indicator consistent
Use a pipe as a separator before long upstream state indicator. This is
consistent with long state indicators for sparse and in-progress
operations (e.g. merge).

For comparison, `__git_ps1` examples without upstream state indicator:

(main %)
(main *%)
(main|SPARSE)
(main %|SPARSE)
(main *%|SPARSE)
(main|SPARSE|REBASE 1/2)
(main %|SPARSE|REBASE 1/2)

Note that if there are long state indicators, they appear after short
state indicators if there are any, or after the branch name if there are
no short state indicators. Each long state indicator begins with a pipe
(`|`) as a separator.

Before/after examples with long upstream state indicator:

0ec7c23cdc git-prompt: make upstream state indicator location consistent
Make upstream state indicator location more consistent with similar
state indicators (e.g. sparse). Group the short upstream state indicator
(`=`, `<`, `>`, or `<>`) with other short state indicators immediately
after the branch name. Previously short and long upstream state
indicators appeared after all other state indicators.

Use a separator (`SP` or `GIT_PS1_STATESEPARATOR`) between branch name
and short upstream state indicator. Previously the short upstream state
indicator would sometimes appear directly adjacent to the branch name
instead of being separated.

For comparison, `__git_ps1` examples without upstream state indicator:
(main)

(main *%)
(main|SPARSE)
(main %|SPARSE)
(main *%|SPARSE)
(main|SPARSE|REBASE 1/2)

Note that if there are short state indicators, they appear together
after the branch name and separated from it by `SP` or

4369e3a1a3 hooks: fix "invoked hook" regression in a8cc594333
Fix a regression in a8cc594333 (hooks: fix an obscure TOCTOU "did we
just run a hook?" race, 2022-03-07): The "invoked_hook" variable
passed to run_commit_hook() wasn't passed forward to run_hooks_opt(),
as push_to_checkout() in that commit correctly did.

Whether we ran the code contingent on having run the hook or not was
thus undefined, but in practice on most (all?) modern platforms we'd
have run it (almost?) all the time, since stack variables will get
initialized to some random value, which most of the time isn't "0".

This bug was revealed by running e.g. "t5537-fetch-shallow.sh" with
the --valgrind option. Unfortunately running the whole test suite with
--valgrind is really slow, so we didn't have a CI job that spotted
this. The --valgrind output was:

    ==31275== Conditional jump or move depends on uninitialised value(s)
    ==31275==    at 0x43C63F: prepare_to_commit (commit.c:1058)

bdff97a3f6 rebase: set REF_HEAD_DETACH in checkout_up_to_date()
"git rebase A B" where B is not a commit should behave as if the
HEAD got detached at B and then the detached HEAD got rebased on top
of A.  A bug however overwrites the current branch to point at B,
when B is a descendant of A (i.e. the rebase ends up being a
fast-forward).  See [1] for the original bug report.

The callstack from checkout_up_to_date() is the following:

cmd_rebase()
-> checkout_up_to_date()
   -> reset_head()
      -> update_refs()
         -> update_ref()

When B is not a valid branch but an oid, rebase sets the head_name
of rebase_options to NULL. This value gets passed down this call
chain through the branch member of reset_head_opts also getting set
to NULL all the way to update_refs().

Then update_refs() checks ropts.branch to decide whether or not to switch
branches. If ropts.branch is NULL, it calls update_ref() to update HEAD.
At this point however, from rebase's point of view, we want a detached
HEAD. But, since checkout_up_to_date() does not set the RESET_HEAD_DETACH
flag, the update_ref() call will deference HEAD and update the branch its
pointing to. We want the HEAD detached at B instead.

Fix this bug by adding the RESET_HEAD_DETACH flag in
checkout_up_to_date if B is not a valid branch, so that once
reset_head() calls update_refs(), it calls update_ref() with
REF_NO_DEREF which updates HEAD directly intead of deferencing it
and updating the branch that HEAD points to.

Also add a test to ensure the correct behavior.

77ab58c091 rebase: use test_commit helper in setup
To prepare for the next commit that will test rebase with oids instead
of branch names, update the rebase setup test to add a couple of tags we
can use. This uses the test_commit helper so we can replace some lines
that add a commit manually.

Setting logAllRefUpdates is not necessary because it's on by default for
repositories with a working tree.
