0f6f5a4022 git config --get-colorbool
This adds an option to help scripts find out color settings from
the configuration file.

    git config --get-colorbool color.diff

inspects color.diff variable, and exits with status 0 (i.e. success) if
color is to be used.  It exits with status 1 otherwise.

If a script wants "true"/"false" answer to the standard output of the
command, it can pass an additional boolean parameter to its command
line, telling if its standard output is a terminal, like this:

    git config --get-colorbool color.diff true

When called like this, the command outputs "true" to its standard output
if color is to be used (i.e. "color.diff" says "always", "auto", or
"true"), and "false" otherwise.

694a577519 git-branch --contains=commit
This teaches git-branch to limit its listing to branches that
are descendants to the named commit.

When you are using many topic branches, you often would want to
see which branch already includes a commit, so that you know
which can and cannot be rewound without disrupting other people.

One thing that sometimes happens to me is:

 * Somebody sends a patch that is a good maint material.  I
   apply it to 'maint':

     $ git checkout maint
     $ git am -3 -s obvious-fix.patch

 * Then somebody else sends another patch that is possibly a
   good maint material, but I'd want to cook it in 'next' to be
   extra sure.  I fork a topic from 'maint' and apply the patch:

     $ git checkout -b xx/maint-fix-foo
     $ git am -3 -s ,xx-maint-fix-foo.patch

 * A minor typo is found in the "obvious-fix.patch".

The above happens without pushing the results out, so I can
freely recover from it by amending 'maint', as long as I do not
forget to rebase the topics that were forked previously.

With this patch, I can do this to find out which topic
branches already contain the faulty commit:

    $ git branch --contains=maint^
      xx/maint-fix-foo

so I can rebase the xx/maint-fix-foo branch before merging it
to 'next'.

4593fb8405 format-patch -s: add MIME encoding header if signer's name requires so
When the body of the commit log message contains a non-ASCII character,
format-patch correctly emitted the encoding header to mark the resulting
message as such.  However, if the original message was fully ASCII, the
command line switch "-s" was given to add a new sign-off, and
the signer's name was not ASCII only, the resulting message would have
contained non-ASCII character but was not marked as such.

674d172730 Rework pretty_print_commit to use strbufs instead of custom buffers.
Also remove the "len" parameter, as:
  (1) it was used as a max boundary, and every caller used ~0u
  (2) we check for final NUL no matter what, so it doesn't help for speed.

  As a result most of the pp_* function takes 3 arguments less, and we need
a lot less local variables, this makes the code way more readable, and
easier to extend if needed.

  This patch also fixes some spacing and cosmetic issues.

6f084a56fc branch --track: code cleanup and saner handling of local branches
This patch cleans up some complicated code, and replaces it with a
cleaner version, using code from remote.[ch], which got extended a
little in the process.  This also enables us to fix two cases:

The earlier "fix" to setup tracking only when the original ref started
with "refs/remotes" is wrong.  You are absolutely allowed to use a
separate layout for your tracking branches.  The correct fix, of course,
is to set up tracking information only when there is a matching
remote.<nick>.fetch line containing a colon.

Another corner case was not handled properly.  If two remotes write to
the original ref, just warn the user and do not set up tracking.

4017761fd8 branch.autosetupmerge: allow boolean values, or "all"
Junio noticed that switching on autosetupmerge unilaterally started
cluttering the config for local branches.  That is not the original
intention of branch.autosetupmerge, which was meant purely for
convenience when branching off of remote branches, but that semantics
got lost somewhere.

If you still want that "new" behavior, you can switch
branch.autosetupmerge to the value "all".  Otherwise, it is interpreted
as a boolean, which triggers setting up defaults _only_ when branching
off of a remote branch, i.e. the originally intended behavior.

80583c0ef6 Lift 16kB limit of log message output
Traditionally we had 16kB limit when formatting log messages for
output, because it was easier to arrange for the caller to have
a reasonably big buffer and pass it down without ever worrying
about reallocating.

This changes the calling convention of pretty_print_commit() to
lift this limit.  Instead of the buffer and remaining length, it
now takes a pointer to the pointer that points at the allocated
buffer, and another pointer to the location that stores the
allocated length, and reallocates the buffer as necessary.

To support the user format, the error return of interpolate()
needed to be changed.  It used to return a bool telling "Ok the
result fits", or "Sorry, I had to truncate it".  Now it returns
0 on success, and returns the size of the buffer it wants in
order to fit the whole result.

9debc3241b git-fetch, git-branch: Support local --track via a special remote '.'
This patch adds support for a dummy remote '.' to avoid having
to declare a fake remote like

        [remote "local"]
                url = .
                fetch = refs/heads/*:refs/heads/*

Such a builtin remote simplifies the operation of "git-fetch",
which will populate FETCH_HEAD but will not pretend that two
repositories are in use, will not create a thin pack, and will
not perform any useless remapping of names.  The speed
improvement is around 20%, and it should improve more if
"git-fetch" is converted to a builtin.

To this end, git-parse-remote is grown with a new kind of
remote, 'builtin'.  In git-fetch.sh, we treat the builtin remote
specially in that it needs no pack/store operations.  In fact,
doing git-fetch on a builtin remote will simply populate
FETCH_HEAD appropriately.

The patch also improves of the --track/--no-track support,
extending it so that branch.<name>.remote items referring '.'
can be created.  Finally, it fixes a typo in git-checkout.sh.

0746d19a82 git-branch, git-checkout: autosetup for remote branch tracking
In order to track and build on top of a branch 'topic' you track from
your upstream repository, you often would end up doing this sequence:

  git checkout -b mytopic origin/topic
  git config --add branch.mytopic.remote origin
  git config --add branch.mytopic.merge refs/heads/topic

This would first fork your own 'mytopic' branch from the 'topic'
branch you track from the 'origin' repository; then it would set up two
configuration variables so that 'git pull' without parameters does the
right thing while you are on your own 'mytopic' branch.

This commit adds a --track option to git-branch, so that "git
branch --track mytopic origin/topic" performs the latter two actions
when creating your 'mytopic' branch.

If the configuration variable branch.autosetupmerge is set to true, you
do not have to pass the --track option explicitly; further patches in
this series allow setting the variable with a "git remote add" option.
The configuration variable is off by default, and there is a --no-track
option to countermand it even if the variable is set.

3a55602eec General const correctness fixes
We shouldn't attempt to assign constant strings into char*, as the
string is not writable at runtime.  Likewise we should always be
treating unsigned values as unsigned values, not as signed values.

Most of these are very straightforward.  The only exception is the
(unnecessary) xstrdup/free in builtin-branch.c for the detached
head case.  Since this is a user-level interactive type program
and that particular code path is executed no more than once, I feel
that the extra xstrdup call is well worth the easy elimination of
this warning.

cc44c7655f Mechanical conversion to use prefixcmp()

c847f53712 Detached HEAD (experimental)
This allows "git checkout v1.4.3" to dissociate the HEAD of
repository from any branch.  After this point, "git branch"
starts reporting that you are not on any branch.  You can go
back to an existing branch by saying "git checkout master", for
example.

This is still experimental.  While I think it makes sense to
allow commits on top of detached HEAD, it is rather dangerous
unless you are careful in the current form.  Next "git checkout
master" will obviously lose what you have done, so we might want
to require "git checkout -f" out of a detached HEAD if we find
that the HEAD commit is not an ancestor of any other branches.
There is no such safety valve implemented right now.

On the other hand, the reason the user did not start the ad-hoc
work on a new branch with "git checkout -b" was probably because
the work was of a throw-away nature, so the convenience of not
having that safety valve might be even better.  The user, after
accumulating some commits on top of a detached HEAD, can always
create a new branch with "git checkout -b" not to lose useful
work done while the HEAD was detached.

We'll see.

I just twisted it not to check fast-forwardness with the current
branch when you are removing a tracking branch.  Most likely,
removal of a tracking branch is not because you are "done with"
it (for a local branch, it usually means "you merged it up"),
but because you are not even interested in it.  In other words,
remote tracking branches are more like tags than branches.

753f96a455 branch --color: change default color selection.
Showing local and remote branches in green and red was simply
overkill, as all we wanted was to make it easy to tell them
apart (local ones can be built on top by committing, but the
remote tracking ones can't).

Use plain coloring for local branches and paint remotes in red.

a1158caead Colourise git-branch output
I wanted to have a visual indication of which branches are local and
which are remote in git-branch -a output; however Junio was concerned
that someone might be using the output in a script.  This patch
addresses the problem by colouring the git-branch output - which in
"auto" mode won't be activated.

I've based it off the colouring code for builtin-diff.c; which means
there is a branch color configuration variable that needs setting to
something before the color will appear.

The colour parameter is "color.branch" rather than "branch.color" to
avoid clashing with the default namespace for default branch merge
definitions.

This patch chooses green for local, red for remote and bold green for
current.

678d0f4cbf git-branch: let caller specify logmsg
This changes the signature of rename_ref() in refs.[hc] to include a
logmessage for the reflogs.

Also, builtin-branch.c is modified to provide a proper logmessage + call
setup_ident() before any logmessages are written.

c976d415e5 git-branch: add options and tests for branch renaming
Extend git-branch with the following options:

  git-branch -m|-M [<oldbranch>] newbranch

The -M variation is required to force renaming over an exsisting
branchname.

This also indroduces $GIT_DIR/RENAME_REF which is a "metabranch"
used when renaming branches. It will always hold the original sha1
for the latest renamed branch.

Additionally, if $GIT_DIR/logs/RENAME_REF exists, all branch rename
events are logged there.

Finally, some testcases are added to verify the new options.

67affd5173 git-branch -D: make it work even when on a yet-to-be-born branch
This makes "git branch -D other_branch" work even when HEAD
points at a yet-to-be-born branch.

Earlier, we checked the HEAD ref for the purpose of "subset"
check even when the deletion was forced (i.e. not -d but -D).
Because of this, you cannot delete a branch even with -D while
on a yet-to-be-born branch.

With this change, the following sequence that now works:

	mkdir newdir && cd newdir
	git init-db
	git fetch -k $other_repo refs/heads/master:refs/heads/othre
	# oops, typo
	git branch other othre
	git branch -D othre
