de90ff81f3 docs: clarify git-branch --list behavior
It was not clear from the "description" section of git-branch(1)
that using a <pattern> meant that you _had_ to use the --list
option. Let's clarify that, and while we're at it, reword some
clunky and ambiguous sentences.

9ef43dd7ad CodingGuidelines: add Python coding guidelines
These are kept short by simply deferring to PEP-8.  Most of the Python
code in Git is already very close to this style (some things in contrib/
are not).

Rationale for version suggestions:

 - Amongst the noise in [1], there isn't any disagreement about using
   2.6 as a base (see also [2]), although Brandon Casey recently added
   support for 2.4 and 2.5 to git-p4 [3].

 - Restricting ourselves to 2.6+ makes aiming for Python 3 compatibility
   significantly easier [4].

 - Advocating Python 3 support in all scripts is currently unrealistic
   because:

     - 'p4 -G' provides output in a format that is very hard to use with
       Python 3 (and its documentation claims Python 3 is unsupported).

     - Mercurial does not support Python 3.

     - Bazaar does not support Python 3.

 - But we should try to make new scripts compatible with Python 3
   because all new Python development is happening on version 3 and the
   Python community will eventually stop supporting Python 2 [5].

 - Python 3.1 is required to support the 'surrogateescape' error handler
   for encoding/decodng filenames to/from Unicode strings and Python 3.0
   is not longer supported.

070c57df42 Merge branch 'rr/minimal-stat'
Some reimplementations of Git does not write all the stat info back
to the index due to their implementation limitations (e.g. jgit
running on Java).  A configuration option can tell Git to ignore
changes to most of the stat fields and only pay attention to mtime
and size, which these implementations can reliably update.  This
avoids excessive revalidation of contents.

  Enable minimal stat checking

0fa2eb530f add: warn when -u or -A is used without pathspec
Most Git commands that can be used with or without pathspec operate
tree-wide by default, the pathspec being used to restrict their
scope.  A few exceptions are: 'git grep', 'git clean', 'git add -u'
and 'git add -A'.  When run in a subdirectory without pathspec, they
operate only on paths in the current directory.

The inconsistency of 'git add -u' and 'git add -A' is particularly
problematic since other 'git add' subcommands (namely 'git add -p'
and 'git add -e') are tree-wide by default.  It also means that "git
add -u && git commit" will record a state that is different from
what is recorded with "git commit -a".

Flipping the default now is unacceptable, so let's start training
users to type 'git add -u|-A :/' or 'git add -u|-A .' explicitly, to
prepare for the next steps:

* forbid 'git add -u|-A' without pathspec (like 'git add' without
  option)

* much later, maybe, re-allow 'git add -u|-A' without pathspec, that
  will add all tracked and modified files, or all files, tree-wide.

A nice side effect of this patch is that it makes the :/ magic
pathspec easier to discover for users.

When the command is called from the root of the tree, there is no
ambiguity and no need to change the behavior, hence no need to warn.

75e5c0dc55 push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCE
When we push to update an existing ref, if:

 * the object at the tip of the remote is not a commit; or
 * the object we are pushing is not a commit,

it won't be correct to suggest to fetch, integrate and push again,
as the old and new objects will not "merge".  We should explain that
the push must be forced when there is a non-committish object is
involved in such a case.

If we do not have the current object at the tip of the remote, we do
not even know that object, when fetched, is something that can be
merged.  In such a case, suggesting to pull first just like
non-fast-forward case may not be technically correct, but in
practice, most such failures are seen when you try to push your work
to a branch without knowing that somebody else already pushed to
update the same branch since you forked, so "pull first" would work
as a suggestion most of the time.  And if the object at the tip is
not a commit, "pull first" will fail, without making any permanent
damage.  As a side effect, it also makes the error message the user
will get during the next "push" attempt easier to understand, now
the user is aware that a non-commit object is involved.

In these cases, the current code already rejects such a push on the
client end, but we used the same error and advice messages as the
ones used when rejecting a non-fast-forward push, i.e. pull from
there and integrate before pushing again.

Introduce new rejection reasons and reword the messages
appropriately.

1187ec99b9 git-cvsimport.txt: cvsps-2 is deprecated
git-cvsimport relies on version 2 of cvsps and does not work with the
new version 3.  Since cvsps 3.x does not currently work as well as
version 2 for incremental import, document this fact.

Specifically, there is no way to make new git-cvsimport that supports
cvsps 3.x and have a seamless transition for existing users since cvsps
3.x needs a time from which to continue importing and git-cvsimport does
not save the time of the last import or import into a specific namespace
so there is no safe way to calculate the time of the last import.

c08e4d5b5c Enable minimal stat checking
Specifically the fields uid, gid, ctime, ino and dev are set to zero
by JGit. Other implementations, eg. Git in cygwin are allegedly also
somewhat incompatible with Git For Windows and on *nix platforms
the resolution of the timestamps may differ.

Any stat checking by git will then need to check content, which may
be very slow, particularly on Windows. Since mtime and size
is typically enough we should allow the user to tell git to avoid
checking these fields if they are set to zero in the index.

This change introduces a core.checkstat config option where the
the user can select to check all fields (default), or just size
and the whole second part of mtime (minimal).

Add support for a pre-push hook which can be used to determine if the
set of refs to be pushed is suitable for the target repository.  The
hook is run with two arguments specifying the name and location of the
destination repository.

Information about what is to be pushed is provided by sending lines of
the following form to the hook's standard input:

  <local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF

If the hook exits with a non-zero status, the push will be aborted.

This will allow the script to determine if the push is acceptable based
on the target repository and branch(es), the commits which are to be
pushed, and even the source branches in some cases.

2934a484fd git-svn: teach find-rev to find near matches
When a single SVN repository is split into multiple Git repositories
many SVN revisions will exist in only one of the Git repositories
created.  For some projects the only way to build a working artifact is
to check out corresponding versions of various repositories, with no
indication of what those are in the Git world - in the SVN world the
revision numbers are sufficient.

By adding "--before" to "git-svn find-rev" we can say "tell me what this
repository looked like when that other repository looked like this":

    git svn find-rev --before \
        r$(git --git-dir=/over/there.git svn find-rev HEAD)

The support we offer these use cases is not very friendly to the end

 - Don't do it.  Avoid such a line by rewrapping or indenting; and

 - Use --cleanup=whitespace but remove all the hint lines we add.

Give them a way to set a custom comment char, e.g.

so that they do not have to do either of the two workarounds.

Some users or projects prefer different algorithms over others, e.g.
patience over myers or similar. However, specifying appropriate
argument every time diff is to be used is impractical. Moreover,
creating an alias doesn't play nicely with other tools based on diff
(git-show for instance). Hence, a configuration variable which is able
to set specific algorithm is needed. For now, these four values are
accepted: 'myers' (which has the same effect as not setting the config
variable at all), 'minimal', 'patience' and 'histogram'.
