A test fix.

"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.
cf. <20170820090629.tumvqwzkromcykjf@sigill.intra.peff.net>

* 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:

"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.

Test portability fix for BSDs.

"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

Some versions of GnuPG fails to kill gpg-agent it auto-spawned
and such a left-over agent can interfere with a test.  Work it
around by attempting to kill one before starting a new test.

* st/lib-gpg-kill-stray-agent:
  t: lib-gpg: flush gpg agent on startup

A recently added test for the "credential-cache" helper revealed
that EOF detection done around the time the connection to the cache
daemon is torn down were flaky.  This was fixed by reacting to
ECONNRESET and behaving as if we got an EOF.

* dl/credential-cache-socket-in-xdg-cache:
  credential-cache: interpret an ECONNRESET as an EOF

When a directory is not readable, "gitweb" fails to build the
project list.  Work this around by skipping such a directory.

It might end up hiding a problem under the rug and a better
solution might be to loudly complain to the administrator pointing
out the problematic directory, but this will at least make it
"work".

* hb/gitweb-project-list:
  gitweb: skip unreadable subdirectories

"git commit" when seeing an totally empty message said "you did not
edit the message", which is clearly wrong.  The message has been
corrected.

* ks/commit-abort-on-empty-message-fix:
