Merge branch 'jc/cvsimport-upgrade' into pu

The most important part of this series is the addition of the new
cvsimport by Eric Raymond that works with cvsps 3.x.  Given some
distros have inertia to be conservative, Git with cvsimport that
does not work with both 3.x will block adoption of cvsps 3.x by
them, and shipping Git with cvsimport that does not work with cvsps
2.x will block such a version of Git, so we'll do the proven "both
old and new are available, but we aim to deprecate and remove the
old one in due time" strategy that we used successfully in the
past.

* jc/cvsimport-upgrade:
  t9600: adjust for new cvsimport
  t9600: further prepare for sharing
  cvsimport-3: add a sample test
  cvsimport: make tests reusable for cvsimport-3
  cvsimport: start adding cvsps 3.x support
  cvsimport: introduce a version-switch wrapper
  cvsimport: allow setting a custom cvsps (2.x) program name
  Makefile: add description on PERL/PYTHON_PATH

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

Expecting a reroll.

  t4014: do not use echo -n
  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

### Stalled
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 reroll.
$gmane/210151

"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 'mp/complete-paths' into pu

The completion script used to let the default completer to suggest
pathnames, which gave too many irrelevant choices (e.g. "git add"
would not want to add an unmodified path).  Teach it to use a more
git-aware logic to enumerate only relevant ones.

Waiting for area-experts' help and review.

* mp/complete-paths:
  git-completion.bash: add support for path completion
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 '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 '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 'rc/maint-complete-git-p4' into pu

Comment from Pete will need to be addressed ($gmane/206172).

* rc/maint-complete-git-p4:
  Teach git-completion about git p4
Merge branch 'jl/submodule-deinit' into pu

There was no Porcelain way to say "I no longer am interested in
this submodule", once you express your interest in a submodule with
"submodule init".  "submodule deinit" is the way to do so.

Expecting a reroll.
$gmane/212884

* jl/submodule-deinit:
  submodule: add 'deinit' command
