The specification of promisor packfiles (in partial-clone.txt) states
that the .promisor files that accompany packfiles do not matter (just
like .keep files), so whenever a packfile is fetched from the promisor
remote, Git has been writing empty .promisor files. But these files
could contain more useful information.
So instead of writing empty files, write the refs fetched to these
files. This makes it easier to debug issues with partial clones, as we
can identify what refs (and their associated hashes) were fetched at the
time the packfile was downloaded, and if necessary, compare those hashes
against what the promisor remote reports now.
This is implemented by teaching fetch-pack to write its own non-empty
.promisor file whenever it knows the name of the pack's lockfile. This
covers the case wherein the user runs "git fetch" with an internal
protocol or HTTP protocol v2 (fetch_refs_via_pack() in transport.c sets
lock_pack) and with HTTP protocol v0/v1 (fetch_git() in remote-curl.c
passes "--lock-pack" to "fetch-pack").

"git add -i" has been taught to show the total number of hunks and
the hunks that has been processed so far when showing prompts.
* kt/add-i-progress:
add -i: show progress counter in the prompt
"git stash apply" in a subdirectory of a secondary worktree failed
to access the worktree correctly, which has been corrected.
* js/stash-apply-in-secondary-worktree:
stash apply: report status correctly even in a worktree's subdirectory
"git range-diff" segfaulted when diff.noprefix configuration was
used, as it blindly expected the patch it internally generates to
have the standard a/ and b/ prefixes. The command now forces the
internal patch to be built without any prefix, not to be affected
by any end-user configuration.
* js/range-diff-noprefix:
range-diff: internally force `diff.noprefix=true`
A few simplification and bugfixes to PCRE interface.

grep: create a "is_fixed" member in "grep_pat"
grep: consistently use "p->fixed" in compile_regexp()
grep: stop using a custom JIT stack with PCRE v1
grep: stop "using" a custom JIT stack with PCRE v2
grep: remove overly paranoid BUG(...) code
grep: use PCRE v2 for optimized fixed-string search
grep: remove the kwset optimization
grep: drop support for \0 in --fixed-strings <pattern>
grep: make the behavior for NUL-byte in patterns sane
grep tests: move binary pattern tests into their own file
grep tests: move "grep binary" alongside the rest
grep: inline the return value of a function call used only once
t4210: skip more command-line encoding tests on MinGW
grep: don't use PCRE2?_UTF8 with "log --encoding=<non-utf8>"
log tests: test regex backends in "--encode=<enc>" tests
"git rebase -i" showed a wrong HEAD while "reword" open the editor.
* pw/rebase-i-show-HEAD-to-reword:
sequencer: simplify root commit creation
rebase -i: check for updated todo after squash and reword
rebase -i: always update HEAD before rewording
The author names taken from SVN repositories may have extra leading
or trailing whitespaces, which are now munged away.

The code to skip "UTF" and "UTF-" prefix, when computing an advice
message, did not work correctly when the prefix was "UTF", which
has been fixed.
* rs/convert-fix-utf-without-dash:
convert: fix handling of dashless UTF prefix in validate_encoding()
Miscellaneous code clean-ups.
* ah/cleanups:
git_mkstemps_mode(): replace magic numbers with computed value
wrapper: use a loop instead of repetitive statements

commit-graph: remove a duplicate assignment
The rename detection logic sorts a list of rename source candidates
by similarity to pick the best candidate, which means that a tie
between sources with the same similarity is broken by the original
location in the original candidate list (which is sorted by path).
Force the sorting by similarity done with a stable sort, which is
not promised by system supplied qsort(3), to ensure consistent
results across platforms.
* js/diff-rename-force-stable-sort:
diffcore_rename(): use a stable sort
Move git_sort(), a stable sort, into into libgit.a
Correct code that tried to reference all entries in a sparse array
of pointers by mistake.
