"git commit" learned to pay attention to "commit.verbose"
configuration variable and act as if "--verbose" option was
given from the command line.

* pb/commit-verbose-config:
  commit: add a commit.verbose config variable
  t7507-commit-verbose: improve test coverage by testing number of diffs
  parse-options.c: make OPTION_COUNTUP respect "unspecified" values

"git format-patch" learned a new "--base" option to record what
(public, well-known) commit the original series was built on in
its output.

* xy/format-patch-base:
  format-patch: introduce format.useAutoBase configuration
  format-patch: introduce --base=auto option
  format-patch: add '--base' option to record base tree info
  patch-ids: make commit_patch_id() a public helper function

A couple of bugs around core.autocrlf have been fixed.

* tb/core-eol-fix:
  convert.c: ident + core.autocrlf didn't work
  t0027: test cases for combined attributes
  convert: allow core.autocrlf=input and core.eol=crlf
  t0027: make commit_chk_wrnNNO() reliable

The experimental "multiple worktree" feature gains more safety to
forbid operations on a branch that is checked out or being actively
worked on elsewhere, by noticing that e.g. it is being rebased.

* nd/worktree-various-heads:
  branch: do not rename a branch under bisect or rebase
  worktree.c: check whether branch is bisected in another worktree
  wt-status.c: split bisect detection out of wt_status_get_state()
  worktree.c: check whether branch is rebased in another worktree
  worktree.c: avoid referencing to worktrees[i] multiple times
  wt-status.c: make wt_status_check_rebase() work on any worktree
  wt-status.c: split rebase detection out of wt_status_get_state()
  path.c: refactor and add worktree_git_path()
  worktree.c: mark current worktree
  worktree.c: make find_shared_symref() return struct worktree *
  worktree.c: store "id" instead of "git_dir"
  path.c: add git_common_path() and strbuf_git_common_path()
  dir.c: rename str(n)cmp_icase to fspath(n)cmp

"git commit --dry-run" reported "No, no, you cannot commit." in one
case where "git commit" would have allowed you to commit, and this
improves it a little bit ("git commit --dry-run --short" still does
not give you the correct answer, for example).  This is a stop-gap
measure in that "commit --short --dry-run" still gives an incorrect
result.

* ss/commit-dry-run-resolve-merge-to-no-op:
  wt-status.c: set commitable bit if there is a meaningful merge.

Some multi-byte encoding can have a backslash byte as a later part
of one letter, which would confuse "highlight" filter used in
gitweb.

its "lfs pointer" subcommand.

A question by "git send-email" to ask the identity of the sender
has been updated.

  send-email: fix grammo in the prompt that asks e-mail recipients

mmap emulation on Windows has been optimized and work better without
consuming paging store when not needed.

* js/win32-mmap:
  mmap(win32): avoid expensive fstat() call
  mmap(win32): avoid copy-on-write when it is unnecessary
  win32mmap: set errno appropriately

"git mv old new" did not adjust the path for a submodule that lives
as a subdirectory inside old/ directory correctly.

* sb/mv-submodule-fix:
  mv: allow moving nested submodules

The "user.useConfigOnly" configuration variable makes it an error
if users do not explicitly set user.name and user.email.  However,
its check was not done early enough and allowed another error to
trigger, reporting that the default value we guessed from the
system setting was unusable.  This was a suboptimal end-user
experience as we want the users to set user.name/user.email without
relying on the auto-detection at all.

* da/user-useconfigonly:
  ident: give "please tell me" message upon useConfigOnly error
  ident: check for useConfigOnly before auto-detection of name/email

The test scripts for "git p4" (but not "git p4" implementation
itself) has been updated so that they would work even on a system
where the installed version of Python is python 3.

* ld/p4-test-py3:
  git-p4 tests: time_in_seconds should use $PYTHON_PATH
  git-p4 tests: work with python3 as well as python2
  git-p4 tests: cd to / before running python

Documentation for "git merge --verify-signatures" has been updated
to clarify that the signature of only the commit at the tip is
verified.  Also the phrasing used for signature and key validity is
adjusted to align with that used by OpenPGP.

On Windows, .git and optionally any files whose name starts with a
dot are now marked as hidden, with a core.hideDotFiles knob to
customize this behaviour.

Running tests with '-x' option to trace the individual command
executions is a useful way to debug test scripts, but some tests
that capture the standard error stream and check what the command
said can be broken with the trace output mixed in.  When running
our tests under "bash", however, we can redirect the trace output
to another file descriptor to keep the standard error of programs
being tested intact.

* jk/test-send-sh-x-trace-elsewhere:
  test-lib: set BASH_XTRACEFD automatically

Update tests for "http.extraHeaders=<header>" to be portable back
to Apache 2.2 (the original depended on <RequireAll/> which is a
more recent feature).

  submodule: ensure that -c http.extraheader is heeded
  t5551: make the test for extra HTTP headers more robust
  tests: adjust the configuration for Apache 2.2

Portability enhancement for "rebase -i" to help platforms whose
shell does not like "for i in <empty>" (which is not POSIX-kosher).

* jk/rebase-interative-eval-fix:
  rebase--interactive: avoid empty list in shell for-loop

"git fsck" learned to catch NUL byte in a commit object as
potential error and warn.

* jc/fsck-nul-in-commit:
  fsck: detect and warn a commit with embedded NUL
  fsck_commit_buffer(): do not special case the last validation

Switching between 'master' and 'next', between which the paths to
test helper binaries have changed, did not update bin-wrappers/*
scripts used in tests, causing false test failures.

CI test was taught to build documentation pages.
