"git archive" did not work well with pathspecs and the
export-ignore attribute.

We may want to resurrect the "we don't archive an empty directory"
bonus patch, but I do not mind merging the above early to 'next'
and leave it as a separate follow-up enhancement.

* rs/archive-excluded-directory:
  archive: don't queue excluded directories
  archive: factor out helper functions for handling attributes
  t5001: add tests for export-ignore attributes and exclude pathspecs

Killing "git merge --edit" before the editor returns control left
the repository in a state with MERGE_MSG but without MERGE_HEAD,
which incorrectly tells the subsequent "git commit" that there was
a squash merge in progress.  This has been fixed.

* mg/killed-merge:
  merge: save merge state earlier
  merge: split write_merge_state in two
  merge: clarify call chain
  Documentation/git-merge: explain --continue

"git apply" that is used as a better "patch -p1" failed to apply a
taken from a file with CRLF line endings to a file with CRLF line
endings.  The root cause was because it misused convert_to_git()
that tried to do "safe-crlf" processing by looking at the index
entry at the same path, which is a nonsense---in that mode, "apply"
is not working on the data in (or derived from) the index at all.
This has been fixed.

* tb/apply-with-crlf:
  apply: file commited with CRLF should roundtrip diff and apply
  convert: add SAFE_CRLF_KEEP_CRLF

When handshake with a subprocess filter notices that the process
asked for an unknown capability, Git did not report what program
the offending subprocess was running.  This has been corrected.

We may want a follow-up fix to tighten the error checking, though.

* cc/subprocess-handshake-missing-capabilities:
  sub-process: print the cmd when a capability is unsupported

"git grep -L" and "git grep --quiet -L" reported different exit
codes; this has been corrected.

* as/grep-quiet-no-match-exit-code-fix:
  git-grep: correct exit code with --quiet and -L

bash 4.4 or newer gave a warning on NUL byte in command
substitution done in "git stash"; this has been squelched.

* kd/stash-with-bash-4.4:
  stash: prevent warning about null bytes in input

Memory leak in an error codepath has been plugged.

* rs/win32-syslog-leakfix:
  win32: plug memory leak on realloc() failure in syslog()

* rs/fsck-obj-leakfix:
  fsck: free buffers on error in fsck_obj()

"git svn" used with "--localtime" option did not compute the tz
offset for the timestamp in question and instead always used the
current time, which has been corrected.

* ur/svn-local-zone:
  git svn fetch: Create correct commit timestamp when using --localtime

"git am -s" has been taught that some input may end with a trailer
block that is not Signed-off-by: and it should refrain from adding
an extra blank line before adding a new sign-off in such a case.

* pw/am-signoff:
  am: fix signoff when other trailers are present

Portability fix.

* rs/in-obsd-basename-dirname-take-const:
  test-path-utils: handle const parameter of basename and dirname

Test portability fix.

* rs/t4062-obsd:
  t4062: use less than 256 repetitions in regex

Test portability fix for BSDs.

* rs/obsd-getcwd-workaround:
  t0001: skip test with restrictive permissions if getpwd(3) respects them

"git clone --recurse-submodules --quiet" did not pass the quiet
option down to submodules.

* bw/clone-recursive-quiet:
  clone: teach recursive clones to respect -q

Commands like "git rebase" accepted the --rerere-autoupdate option
from the command line, but did not always use it.  This has been
fixed.

* pw/sequence-rerere-autoupdate:
  cherry-pick/revert: reject --rerere-autoupdate when continuing
  cherry-pick/revert: remember --rerere-autoupdate
  t3504: use test_commit
  rebase -i: honor --rerere-autoupdate
  rebase: honor --rerere-autoupdate
  am: remember --rerere-autoupdate setting

"git push --recurse-submodules $there HEAD:$target" was not
propagated down to the submodules, but now it is.

* bw/push-options-recursively-to-submodules:
  submodule--helper: teach push-check to handle HEAD

The "tag.pager" configuration variable was useless for those who
actually create tag objects, as it interfered with the use of an
editor.  A new mechanism has been introduced for commands to enable
pager depending on what operation is being carried out to fix this,
and then "git tag -l" is made to run pager by default.

If this works out OK, I think there are low-hanging fruits in
other commands like "git branch" that outputs long list in one mode
while taking input in another.

* ma/pager-per-subcommand-action:
  git.c: ignore pager.* when launching builtin as dashed external
  tag: change default of `pager.tag` to "on"
  tag: respect `pager.tag` in list-mode only
  t7006: add tests for how git tag paginates
  git.c: provide setup_auto_pager()
  git.c: let builtins opt for handling `pager.foo` themselves
  builtin.h: take over documentation from api-builtin.txt

"git log --tag=no-such-tag" showed log starting from HEAD, which
has been fixed---it now shows nothing.

* jk/rev-list-empty-input:
  revision: do not fallback to default when rev_input_given is set
  rev-list: don't show usage when we see empty ref patterns
  revision: add rev_input_given flag
  t6018: flesh out empty input/output rev-list tests
