This new function implements the functionality of RCS merge, but
in-memory. It returns < 0 on error, otherwise the number of conflicts.
Finding the conflicting lines can be a very expensive task. You can
control the eagerness of this algorithm:
- a level value of 0 means that all overlapping changes are treated
as conflicts,
- a value of 1 means that if the overlapping changes are identical,
it is not treated as a conflict.
- If you set level to 2, overlapping changes will be analyzed, so that
almost identical changes will not result in huge conflicts. Rather,
only the conflicting lines will be shown inside conflict markers.
With each increasing level, the algorithm gets slower, but more accurate.
Note that the code for level 2 depends on the simple definition of
mmfile_t specific to git, and therefore it will be harder to port that
to LibXDiff.

git-svn: avoid fetching files twice in the same revision
SVN is not entirely consistent in returning log information and
sometimes returns file information when adding subdirectories,
and sometimes it does not (only returning information about the
directory that was added). This caused git-svn to occasionally
add a file to the list of files to be fetched twice. Now we
change the data structure to be hash to avoid repeated fetches.
As of now (in master), this only affects repositories fetched
without deltas enabled (file://, and when manually overriden
with GIT_SVN_DELTA_FETCH=0); so this bug mainly affects users of
1.4.4.1 and maint.
Thanks to Florian Weimer for reporting this bug.

Teaching "commit -a" without saying that it is a shortcut for

Commit 35e65ecc broke completion of local refs, e.g. "git pull . fo<tab>"
no longer would complete to "foo". Instead it printed out an internal
git error ("fatal: Not a git repository: '.'").
The break occurred when I tried to improve performance by switching from
git-peek-remote to git-for-each-ref. Apparently git-peek-remote will
drop into directory "$1/.git" (where $1 is its first parameter) if it
is given a repository with a working directory. This allowed the bash
completion code to work properly even though it was not handing over
the true repository directory.
So now we do a stat in bash to see if we need to add "/.git" to the
path string before running any command with --git-dir.
I also tried to optimize away two "git rev-parse --git-dir" invocations
in common cases like "git log fo<tab>" as typically the user is in the
top level directory of their project and therefore the .git subdirectory
is in the current working directory. This should make a difference on
systems where fork+exec might take a little while.

Because of this, you cannot delete a branch even with -D while

git-clone: stop dumb protocol from copying refs outside heads/ and tags/.
Most notably, the original code first copied refs/remotes/ that
remote side had to local, and overwrote them by mapping refs/heads/
from the remote when a dumb protocol transport was used.
This makes the clone behaviour by dumb protocol in line with the
git native and rsync transports.

replace the destination ref with the object known as $src on the

git-cvsimport: add support for CVS pserver method HTTP/1.x proxying
This patch adds support for 'proxy' and 'proxyport' connection options
when using the pserver method for the CVS Root.
It has been tested with a Squid 2.5.x proxy server.
Quoting from the CVS info manual:
The `gserver' and `pserver' connection methods all accept optional
method options, specified as part of the METHOD string, like so:
:METHOD[;OPTION=ARG...]:
Currently, the only two valid connection options are `proxy', which
takes a hostname as an argument, and `proxyport', which takes a port
number as an argument. These options can be used to connect via an HTTP
tunnel style web proxy. For example, to connect pserver via a web proxy
at www.myproxy.net and port 8000, you would use a method of:
:pserver;proxy=www.myproxy.net;proxyport=8000:
*NOTE: The rest of the connection string is required to connect to
the server as noted in the upcoming sections on password authentication,
gserver and kserver. The example above would only modify the METHOD
portion of the repository name.*
PROXY must be supplied to connect to a CVS server via a proxy
server, but PROXYPORT will default to port 8080 if not supplied.
PROXYPORT may also be set via the CVS_PROXY_PORT environment variable.

refs outside refs/{heads,tags} match less strongly.
This changes the refname matching logic used to decide which ref
is updated with git-send-pack. We used to error out when
pushing 'master' when the other end has both 'master' branch and
a tracking branch 'remotes/$name/master' but with this, 'master'
matches only 'refs/heads/master' when both and no other 'master'
exist.
Pushing 'foo' when both heads/foo and tags/foo exist at the
remote end is still considered an error and you would need to
disambiguate between them by being more explicit.
When neither heads/foo nor tags/foo exists at the remote,
pushing 'foo' when there is only remotes/origin/foo is not
ambiguous, while it still is ambiguous when there are more than
one such weaker match (remotes/origin/foo and remotes/alt/foo,
for example).

the context is useless. This patch increases that buffer to 80

We can't rely on sizeof(struct zip_*) returning the sum of
all struct members. At least on ARM padding is added at the
end, as Gerrit Pape reported. This fixes the problem but
still lets the compiler do the summing by introducing
explicit padding at the end of the structs and then taking
its offset as the combined size of the preceding members.
As Junio correctly notes, the _end[] marker array's size
must be greater than zero for compatibility with compilers
other than gcc. The space wasted by the markers can safely
be neglected because we only have one instance of each
struct, i.e. in sum 3 wasted bytes on i386, and 0 on ARM. :)
We still rely on the compiler to not add padding between the
struct members, but that's reasonable given that all of them
are unsigned char arrays.
