When fast-export encounters a commit with an 'encoding' header, it tries
to reencode in UTF-8 and then drops the encoding header. However, if it
fails to reencode in UTF-8 because e.g. one of the characters in the
commit message was invalid in the old encoding, then we need to retain
the original encoding or otherwise we lose information needed to
understand all the other (valid) characters in the original commit
message.

Since git supports commit messages with an encoding other than UTF-8,
allow fast-import to import such commits. This may be useful for folks
who do not want to reencode commit messages from an external system, and
may also be useful to achieve reversible history rewrites (e.g. sha1sum
<-> sha256sum transitions or subtree work) with git repositories that
have used specialized encodings in their commit history.

This test used an author with non-ascii characters in the name, but no
special commit message. It then grep'ed for those non-ascii characters,
but those are guaranteed to exist regardless of the reencoding process
since the reencoding only affects the commit message, not the author or
committer names. As such, the test would work even if the re-encoding
process simply stripped the commit message entirely. Modify the test to
actually check that the reencoding into UTF-8 worked.

Build with gettext breaks on recent macOS w/ Homebrew when
/usr/local/bin is not on PATH, which has been corrected.
* js/macos-gettext-build:
macOS: make sure that gettext is found
The recently added feature to add addresses that are on
anything-by: trailers in 'git send-email' was found to be way too
eager and considered nonsense strings as if they can be legitimate
beginning of *-by: trailer. This has been tightened.
* bs/sendemail-tighten-anything-by:
send-email: don't cc *-by lines with '-' prefix
"git send-email" has been taught to use quoted-printable when the
payload contains carriage-return. The use of the mechanism is in
line with the design originally added the codepath that chooses QP
when the payload has overly long lines.
* bc/send-email-qp-cr:
send-email: default to quoted-printable when CR is present
"git submodule foreach <command> --quiet" did not pass the option
down correctly, which has been corrected.
* nd/submodule-foreach-quiet:
submodule foreach: fix "<command> --quiet" not being respected
The GETTEXT_POISON test option has been quite broken ever since it
was made runtime-tunable, which has been fixed.
* jc/gettext-test-fix:
gettext tests: export the restored GIT_TEST_GETTEXT_POISON
Code clean-up and a fix for "git fetch" by an explicit object name
(as opposed to fetching refs by name).
* jk/fetch-reachability-error-fix:
fetch: do not consider peeled tags as advertised tips
remote.c: make singular free_ref() public
fetch: use free_refs()
pkt-line: prepare buffer before handling ERR packets
upload-pack: send ERR packet for non-tip objects
t5530: check protocol response for "not our ref"
t5516: drop ok=sigpipe from unreachable-want tests
The code is updated to check the result of memory allocation before
it is used in more places, by using xmalloc and/or xcalloc calls.
* jk/xmalloc:
progress: use xmalloc/xcalloc
xdiff: use xmalloc/xrealloc
xdiff: use git-compat-util
test-prio-queue: use xmalloc
An underallocation in the code to read the untracked cache
extension has been corrected.
* js/untracked-cache-allocfix:
untracked cache: fix off-by-one
"git blame -- path" in a non-bare repository starts blaming from
the working tree, and the same command in a bare repository errors
out because there is no working tree by definition. The command
has been taught to instead start blaming from the commit at HEAD,
which is more useful.
* sg/blame-in-bare-start-at-head:
blame: default to HEAD in a bare repo when no start commit is given
Updating the display with progress message has been cleaned up to
deal better with overlong messages.
* sg/overlong-progress-fix:
progress: break too long progress bar lines
progress: clear previous progress update dynamically
progress: assemble percentage and counters in a strbuf before printing
progress: make display_progress() return void
While running "git diff" in a lazy clone, we can upfront know which
missing blobs we will need, instead of waiting for the on-demand
machinery to discover them one by one. Aim to achieve better
performance by batching the request for these promised blobs.
* jt/batch-fetch-blobs-in-diff:
diff: batch fetching of missing blobs
sha1-file: support OBJECT_INFO_FOR_PREFETCH
Performance fix for "rev-list --parents -- pathspec".
* jk/revision-rewritten-parents-in-prio-queue:
revision: use a prio_queue to hold rewritten parents
Performance fix around "git blame", especially in a linear history
(which is the norm we should optimize for).
* dk/blame-keep-origin-blob:
blame.c: don't drop origin blobs as eagerly

t9300: demonstrate bug with get-mark and empty orphan commits
Fix for protocol v2 support in "git fetch-pack" of shallow clones.
* jt/fetch-no-update-shallow-in-proto-v2:
fetch-pack: respect --no-update-shallow in v2
fetch-pack: call prepare_shallow_info only if v0
A progress indicator has been added to the "index-pack" step, which
often makes users wait for completion during "git clone".
* sg/index-pack-progress:
index-pack: show progress while checking objects
Code cleanup with more careful error checking before using data
read from the commit-graph file.
* ab/commit-graph-fixes:
commit-graph: improve & i18n error messages
commit-graph write: don't die if the existing graph is corrupt
commit-graph verify: detect inability to read the graph
commit-graph: don't pass filename to load_commit_graph_one_fd_st()
commit-graph: don't early exit(1) on e.g. "git status"
commit-graph: fix segfault on e.g. "git status"
commit-graph tests: test a graph that's too small
commit-graph tests: split up corrupt_graph_and_verify()
Fix various glitches in "git gc" around reflog handling.
* ab/gc-reflog:
gc: handle & check gc.reflogExpire config
reflog tests: assert lack of early exit with expiry="never"
reflog tests: test for the "points nowhere" warning
reflog tests: make use of "test_config" idiom
gc: refactor a "call me once" pattern
gc: convert to using the_hash_algo
gc: remove redundant check for gc_auto_threshold
"git checkout -m <other>" was about carrying the differences
between HEAD and the working-tree files forward while checking out
another branch, and ignored the differences between HEAD and the
index. The command has been taught to abort when the index and the
HEAD are different.
* nd/checkout-m:
checkout: prevent losing staged changes with --merge
read-tree: add --quiet
unpack-trees: rename "gently" flag to "quiet"
unpack-trees: keep gently check inside add_rejected_path
"git difftool" can now run outside a repository.
* js/difftool-no-index:
difftool: allow running outside Git worktrees with --no-index
parse-options: make OPT_ARGUMENT() more useful
difftool: remove obsolete (and misleading) comment
"git cherry-pick --options A..B", after giving control back to the
user to ask help resolving a conflicted step, did not honor the
options it originally received, which has been corrected.
* pw/cherry-pick-continue:
cherry-pick --continue: remember options
cherry-pick: demonstrate option amnesia
sequencer: break some long lines
The message given when "git commit -a <paths>" errors out has been
updated.
* nd/commit-a-with-paths-msg-update:
commit: improve error message in "-a <paths>" case

test-lib: introduce 'test_atexit'
t/lib-git-daemon: make sure to kill the 'git-daemon' process
test-lib: fix interrupt handling with 'dash' and '--verbose-log -x'
The scripted version of "git rebase -i" wrote and rewrote the todo
list many times during a single step of its operation, and the
recent C-rewrite made a faithful conversion of the logic to C. The
implementation has been updated to carry necessary information
around in-core to avoid rewriting the same file over and over
unnecessarily.
* ag/sequencer-reduce-rewriting-todo:
rebase--interactive: move transform_todo_file()
sequencer: use edit_todo_list() in complete_action()
rebase-interactive: rewrite edit_todo_list() to handle the initial edit
rebase-interactive: append_todo_help() changes
rebase-interactive: use todo_list_write_to_file() in edit_todo_list()
sequencer: refactor skip_unnecessary_picks() to work on a todo_list
rebase--interactive: move rearrange_squash_in_todo_file()
rebase--interactive: move sequencer_add_exec_commands()
sequencer: change complete_action() to use the refactored functions
sequencer: make sequencer_make_script() write its script to a strbuf
sequencer: refactor rearrange_squash() to work on a todo_list
sequencer: refactor sequencer_add_exec_commands() to work on a todo_list

sequencer: remove the 'arg' field from todo_item
sequencer: make the todo_list structure public
sequencer: changes in parse_insn_buffer()
A new hook "post-index-change" is called when the on-disk index
file changes, which can help e.g. a virtualized working tree
implementation.
* bp/post-index-change-hook:
read-cache: add post-index-change hook
"git mergetool" learned to offer Sublime Merge (smerge) as one of
its backends.
* da/smerge:
contrib/completion: add smerge to the mergetool completion candidates
mergetools: add support for smerge (Sublime Merge)
The tests have been updated not to rely on the abbreviated option
names the parse-options API offers, to protect us from an
abbreviated form of an option that used to be unique within the
command getting non-unique when a new option that share the same
prefix is added.
* js/spell-out-options-in-tests:
tests: disallow the use of abbreviated options (by default)
tests (pack-objects): use the full, unabbreviated `--revs` option
tests (status): spell out the `--find-renames` option in full
tests (push): do not abbreviate the `--follow-tags` option
t5531: avoid using an abbreviated option
t7810: do not abbreviate `--no-exclude-standard` nor `--invert-match`
tests (rebase): spell out the `--force-rebase` option
tests (rebase): spell out the `--keep-empty` option
