Merge branch 'bc/append-signed-off-by' into pu

Expecting a re-roll after a review.

* bc/append-signed-off-by:
  Unify appending signoff in format-patch, commit and sequencer
  format-patch: update append_signoff prototype
  format-patch: stricter S-o-b detection
  t4014: more tests about appending s-o-b lines
  sequencer.c: teach append_signoff to avoid adding a duplicate newline
  sequencer.c: teach append_signoff how to detect duplicate s-o-b
  sequencer.c: always separate "(cherry picked from" from commit body
  sequencer.c: recognize "(cherry picked from ..." as part of s-o-b footer
  t/t3511: add some tests of 'cherry-pick -s' functionality
  t/test-lib-functions.sh: allow to specify the tag name to test_commit
  sequencer.c: remove broken support for rfc2822 continuation in footer
Merge branch 'jc/add-delete-default' into pu

"git add dir/" updated modified files and added new files, but does
not notice removed files, which may be "Huh?" to some users.  They
can of course use "git add -A dir/", but why should they?

Resurrected from graveyard, as I thought it was a worthwhile thing
to do in the longer term.

Waiting for comments.

* jc/add-delete-default:
  git add: notice removal of tracked paths by default
Merge branch 'jc/maint-name-rev' into pu

"git name-rev" names the given revision based on a ref that can be
reached in the smallest number of steps from the rev, but that is
not useful when the caller wants to know which tag is the oldest one
that contains the rev.  This teaches a new mode to the command that
uses the oldest ref among those which contain the rev.

I am not sure if this is worth it; for one thing, even with the help
from notes-cache, it seems to make the "describe --contains" even
slower. Also the command will be unusably slow for a user who does
not have a write access (hence unable to create or update the
notes-cache).

Stalled mostly due to lack of responses.

* jc/maint-name-rev:
  describe --contains: use "name-rev --algorithm=weight"
  name-rev --algorithm=weight: tests and documentation
  name-rev --algorithm=weight: cache the computed weight in notes
  name-rev --algorithm=weight: trivial optimization
  name-rev: --algorithm option
  name_rev: clarify the logic to assign a new tip-name to a commit
  name-rev: lose unnecessary typedef

Conflicts:
	builtin/name-rev.c
Merge branch 'jc/blame-no-follow' into pu

Teaches "--no-follow" option to "git blame" to disable its
whole-file rename detection.

Stalled mostly due to lack of responses.

* jc/blame-no-follow:
  blame: pay attention to --no-follow
  diff: accept --no-follow option
Merge branch 'mo/cvs-server-updates' into pu

Needs review by folks interested in cvsserver.

* mo/cvs-server-updates:
  cvsserver Documentation: new cvs ... -r support
  cvsserver: add t9402 to test branch and tag refs
  cvsserver: support -r and sticky tags for most operations
  cvsserver: Add version awareness to argsfromdir
  cvsserver: generalize getmeta() to recognize commit refs
  cvsserver: implement req_Sticky and related utilities
  cvsserver: add misc commit lookup, file meta data, and file listing functions
  cvsserver: define a tag name character escape mechanism
  cvsserver: cleanup extra slashes in filename arguments
  cvsserver: factor out git-log parsing logic
Merge branch 'as/test-tweaks' into pu

Various minor tweaks to the test framework to paint its output
lines in colors that match what they mean better.

Has the "is this really blue?" issue Peff raised resolved???

* as/test-tweaks:
  tests: paint unexpectedly fixed known breakages in bold red
  tests: test the test framework more thoroughly
  [SQUASH] t/t0000-basic.sh: quoting of TEST_DIRECTORY is screwed up
  tests: refactor mechanics of testing in a sub test-lib
  tests: paint skipped tests in bold blue
  tests: test number comes first in 'not ok $count - $message'
  tests: paint known breakages in bold yellow
Merge branch 'mb/remote-default-nn-origin' into pu

When the user does not specify what remote to interact with, we
often attempt to use 'origin'.  This can now be customized via a
configuration variable.

Expecting a re-roll.

"The first remote becomes the default" bit is better done as a
separate step.

* mb/remote-default-nn-origin:
  Teach get_default_remote to respect remote.default.
  Test that plain "git fetch" uses remote.default when on a detached HEAD.
  Teach clone to set remote.default.
  Teach "git remote" about remote.default.
  Teach remote.c about the remote.default configuration setting.
  Rename remote.c's default_remote_name static variables.

Conflicts:
	builtin/remote.c
	t/t5505-remote.sh
Merge branch 'jc/xprm-generation' into pu

A toy to analyze how bad the clock skews are in histories of real
world projects.

Stalled mostly due to lack of responses.

* jc/xprm-generation:
  test-generation: compute generation numbers and clock skews
Merge branch 'jk/lua-hackery' into pu

Interesting exercise. When we do this for real, we probably would want
to wrap a commit to make it more like an "object" with methods like
"parents", etc.

* jk/lua-hackery:
  pretty: fix up one-off format_commit_message calls
  Minimum compilation fixup
  Makefile: make "lua" a bit more configurable
  add a "lua" pretty format
  add basic lua infrastructure
  pretty: make some commit-parsing helpers more public
Merge branch 'jc/doc-default-format' into pu

Need to address the installation half if this is to be any useful.

* jc/doc-default-format:
  [SQAUSH] allow "cd Doc* && make DEFAULT_DOC_TARGET=..."
  Allow generating a non-default set of documentation
Merge branch 'as/check-ignore' into pu

Duy helped to reroll this.

Expecting a re-roll.

* as/check-ignore:
  t0007: fix tests on Windows
  Documentation/check-ignore: we show the deciding match, not the first
  Add git-check-ignore sub-command
  dir.c: provide free_directory() for reclaiming dir_struct memory
  pathspec.c: move reusable code from builtin/add.c
  dir.c: refactor treat_gitlinks()
  dir.c: keep track of where patterns came from
  dir.c: refactor is_path_excluded()
  dir.c: refactor is_excluded()
  dir.c: refactor is_excluded_from_list()
  dir.c: rename excluded() to is_excluded()
  dir.c: rename excluded_from_list() to is_excluded_from_list()
  dir.c: rename path_excluded() to is_path_excluded()
  dir.c: rename cryptic 'which' variable to more consistent name
Merge branch 'jc/doc-maintainer' into pu

An early draft that is still incomplete.

* jc/doc-maintainer:
  update "howto maintain git"
