We have been trying out a few language features outside c89; the
coding guidelines document did not talk about them and instead had
a blanket ban against them.

* jc/post-c89-rules-doc:
  CodingGuidelines: spell out post-C89 rules

Code restructuring during 2.20 period broke fetching tags via
"import" based transports.

* fc/fetch-with-import-fix:
  fetch: fix regression with transport helpers
  fetch: make the code more understandable
  fetch: trivial cleanup
  t5801 (remote-helpers): add test to fetch tags
  t5801 (remote-helpers): cleanup refspec stuff

The commit-graph file is now part of the "files that the runtime
may keep open file descriptors on, all of which would need to be
closed when done with the object store", and the file descriptor to
an existing commit-graph file now is closed before "gc" finalizes a
new instance to replace it.

* ds/close-object-store:
  packfile: rename close_all_packs to close_object_store
  packfile: close commit-graph in close_all_packs
  commit-graph: use raw_object_store when closing
  commit-graph: extract write_commit_graph_file()
  commit-graph: extract copy_oids_to_commits()
  commit-graph: extract count_distinct_commits()
  commit-graph: extract fill_oids_from_all_packs()
  commit-graph: extract fill_oids_from_commit_hex()
  commit-graph: extract fill_oids_from_packs()
  commit-graph: create write_commit_graph_context
  commit-graph: remove Future Work section
  commit-graph: collapse parameters into flags
  commit-graph: return with errors during write
  commit-graph: fix the_repository reference

"git checkout -p" needs to selectively apply a patch in reverse,
which did not work well.

* pw/add-p-recount:
  add -p: fix checkout -p with pathological context

Code clean-up to avoid signed integer overlaps during binary search.

* rs/avoid-overflow-in-midpoint-computation:
  cleanup: fix possible overflow errors in binary search, part 2

"git interpret-trailers" always treated '#' as the comment
character, regardless of core.commentChar setting, which has been
corrected.

* jk/trailers-use-config:
  interpret-trailers: load default config

"git stash show 23" used to work, but no more after getting
rewritten in C; this regression has been corrected.

* tg/stash-ref-by-index-fix:
  stash: fix show referencing stash index

"git rebase --abort" used to leave refs/rewritten/ when concluding
"git rebase -r", which has been corrected.

* pw/rebase-abort-clean-rewritten:
  rebase --abort/--quit: cleanup refs/rewritten
  sequencer: return errors from sequencer_remove_state()
  rebase: warn if state directory cannot be removed
  rebase: fix a memory leak

An incorrect list of options was cached after command line
completion failed (e.g. trying to complete a command that requires
a repository outside one), which has been corrected.

* nd/completion-no-cache-failure:
  completion: do not cache if --git-completion-helper fails

The code to parse scaled numbers out of configuration files has
been made more robust and also easier to follow.

* rs/config-unit-parsing:
  config: simplify parsing of unit factors
  config: don't multiply in parse_unit_factor()
  config: use unsigned_mult_overflows to check for overflows

The codepath to compute delta islands used to spew progress output
without giving the callers any way to squelch it, which has been
fixed.

* jk/delta-islands-progress-fix:
  delta-islands: respect progress flag

Use "Erase in Line" CSI sequence that is already used in the editor
support to clear cruft in the progress output.

* sg/rebase-progress:
  progress: use term_clear_line()
  rebase: fix garbled progress display with '-x'
  pager: add a helper function to clear the last line in the terminal
  t3404: make the 'rebase.missingCommitsCheck=ignore' test more focused
  t3404: modernize here doc style

"git submodule foreach" did not protect command line options passed
to the command to be run in each submodule correctly, when the
"--recursive" option was in use.

* ms/submodule-foreach-fix:
  submodule foreach: fix recursion of options

The configuration variable rebase.rescheduleFailedExec should be
effective only while running an interactive rebase and should not
affect anything when running an non-interactive one, which was not
the case.  This has been corrected.

* js/rebase-reschedule-applies-only-to-interactive:
  rebase --am: ignore rebase.rescheduleFailedExec

The "git clone" documentation refers to command line options in its
description in the short form; they have been replaced with long
forms to make them more recognisable.

* qn/clone-doc-use-long-form:
  docs: git-clone: list short form of options first
  docs: git-clone: refer to long form of options

"git rm" to resolve a conflicted path leaked an internal message
"needs merge" before actually removing the path, which was
confusing.  This has been corrected.

* jc/denoise-rm-to-resolve:
  rm: resolving by removal is not a warning-worthy event

Window 7 update ;-)

* js/mingw-spawn-with-spaces-in-path:
  mingw: support spawning programs containing spaces in their names

past the end of allocated buffer, which has been fixed.

* sr/gpg-interface-stop-at-the-end:
  gpg-interface: do not scan past the end of buffer

"git clean" silently skipped a path when it cannot lstat() it; now
it gives a warning.

* js/clean-report-too-long-a-path:
  clean: show an error message when the path is too long

"git push --atomic" that goes over the transport-helper (namely,
the smart http transport) failed to prevent refs to be pushed when
it can locally tell that one of the ref update will fail without
having to consult the other end, which has been corrected.

* es/local-atomic-push-failure-with-http:
  transport-helper: avoid var decl in for () loop control
  transport-helper: enforce atomic in push_refs_with_push
