When you do this, existing "blame -C -C" would not find that the
latter half of the file2 came from the existing file1:
... both file1 and file2 are tracked ...
$ cat file1 >>file2
$ git add file1 file2
$ git commit
This is because we avoid the expensive find-copies-harder code
that makes unchanged file (in this case, file1) as a candidate
for copy & paste source when annotating an existing file
(file2). The third -C now allows it. However, this obviously
makes the process very expensive. We've actually seen this
patch before, but I dismissed it because it covers such a narrow
(and arguably stupid) corner case.

The -C option to blame tries to find a section of a preimage
file by running diff against the lines whose origin is still
unknown, and excluding the different parts. The code however
did not cover the case where the tail part of the section
matched, which we handle for the normal non-move/copy codepath.
This breakage was most visible when preimage file matches in its
entirety and failed to pass blame in such a case.

Most other documentation will frequently be read from an installation
of git so will naturally be associated with the installed version.
But these two documents in particular are often read from web pages
while users are still exploring git. It's important to mention
version 1.5.1 since these documents provide example commands that
won't work with previous versions of git.

git-svn dcommit exports commits to Subversion, then imports them back
to git again, and last but not least rebases or resets HEAD to the
last of the new commits. I guess this rebasing is convenient when
using just git, but when the commits to be exported are managed by
StGIT, it's really annoying. So add an option to disable this
behavior. And document it, too!

This is actually a few different changes to request-pull,
making it slightly smarter:
1) Minor cleanup of revision->base variable names, making it
follow the head/headrev naming convention that is already
in use.
2) Compute the merge-base between the two revisions upfront
and reuse that selected merge-base to create the diffstat.
3) Refuse to generate a pull request for branches that have no
existing relationship. These aren't very common and would mess
up our diffstat generation.
4) Disable the PAGER when running shortlog and diff, as these
would otherwise activate the pager for each command when
git-request-pull is run on a tty. Instead users can get the
entire output paged (if desired) using `git -p request-pull`.
5) Use shortlog rather than `git log | git shortlog` now that
recent shortlog versions are able to run the revision listing
internally.
6) Attempt to resolve the input URL using the user's configured
remotes. This is useful if the URL you want the recipient to
see is also the one you used to push your changes. If not a
config-file remote could easily be setup for the public URL
and request-pull could be passed that name instead.
7) Automatically guess and include the remote branch name in the
body of the message. We list the branch name immediately after
the URL, making it easy for the recipient to copy and paste
the entire line onto a `git pull` command line. Rumor has it
Linus likes this format, for exactly that reason.
If multiple branches at the remote match $headrev we take the
first one returned by peek-remote and assume it is suitable.
If no branches are available we warn the user about the problem,
but insert a static string that is not a valid branch name
and would be obvious to anyone reading the message as being
totally incorrect. This allows users to still generate a
template message without network access (for example) and
hand-correct the bits that cannot be verified.

There really isn't any point in turning off .mailmap. The
number of mailmap lookups are bounded by number of lines in the
target file, and the real blame processing is much more
expensive. If it turns out to be too costly, we should optimize
the mailmap lookup itself, instead of avoiding the call.
If the author information of commits of the project are
relatively clean, .mailmap would have only small number of
entries, and the overhead of looking it up will not be high. On
the other hand, if the author information is really screwed up
that a good .mailmap needs to be maintained to run shortlog,
giving uncleaned names in blame output is not helpful at all
either.

This extension allows GNU tar to process file names in excess of the 100
characters defined by the original tar standard. It does this by faking a
file, named '././@LongLink' containing the true file name, and then adding
the file with a truncated name. The idea is that tar without this
extension will write out a file with the long file name, and write the
contents into a file with truncated name.
Unfortunately, GNU tar does a lousy job at times. When truncating results
in a _directory_ name, it will happily use _that_ as a truncated name for
the file.
An example where this actually happens is gcc-4.1.2, where the full path
of the file WeThrowThisExceptionHelper.java truncates _exactly_ before the
basename. So, we have to support that ad-hoc extension.

This concept was lifted from git.git's Makefile, where a similar

After reading the leading contents from a symlink data obtained

forked to hash the remainder (which should match readlink()

the filehandle we read that 'link ' from. This was Ok with Perl
on modern Linux, but on Mac OS, the read in the parent process
slurped more than we asked for in stdio buffer, and the child
