This patch fixes issues mentioned by Junio, Nico and Simon:

- I forgot to convert the usage string when removing the "--" from
  the subcommands,
- a style fix in the bundle_header,
- use xread() instead of read(),
- use write_or_die() instead of write(),
- make the bundle header extensible,
- fail if the whitespace after a sha1 of a reference is missing,
- close() the fds passed to a subprocess,
- in verify_bundle(), do not use "rev-list --stdin", but rather
  pass the revs directly (avoiding a fork()),
- fix a corrupted comment in show_object(), and
- fix the size check in index_pack.

Some workflows require use of repositories on machines that cannot be
connected, preventing use of git-fetch / git-push to transport objects and
references between the repositories.

git-bundle provides an alternate transport mechanism, effectively allowing
git-fetch and git-pull to operate using sneakernet transport. `git-bundle
create` allows the user to create a bundle containing one or more branches
or tags, but with specified basis assumed to exist on the target
repository. At the receiving end, git-bundle acts like git-fetch-pack,
allowing the user to invoke git-fetch or git-pull using the bundle file as
the URL. git-fetch and git-ls-remote determine they have a bundle URL by
checking that the URL points to a file, but are otherwise unchanged in
operation with bundles.

The original patch was done by Mark Levedahl <mdl123@verizon.net>.

It was updated to make git-bundle a builtin, and get rid of the tar
format: now, the first line is supposed to say "# v2 git bundle", the next
lines either contain a prerequisite ("-" followed by the hash of the
needed commit), or a ref (the hash of a commit, followed by the name of
the ref), and finally the pack. As a result, the bundle argument can be
"-" now.

Here's a patch that I think we can merge right now. There may be
other places that need this, but this at least points out the
three places that read/write working tree files for git
update-index, checkout and diff respectively. That should cover
a lot of it [jc: git-apply uses an entirely different codepath
both for reading and writing].

Some day we can actually implement it. In the meantime, this
points out a place for people to start. We *can* even start with
a really simple "we do CRLF conversion automatically, regardless
of filename" kind of approach, that just look at the data (all
three cases have the _full_ file data already in memory) and
says "ok, this is text, so let's convert to/from DOS format
directly".

THAT somebody can write in ten minutes, and it would already
make git much nicer on a DOS/Windows platform, I suspect.

And it would be totally zero-cost if you just make it a config
option (but please make it dynamic with the _default_ just being
0/1 depending on whether it's UNIX/Windows, just so that UNIX
people can _test_ it easily).

Some of the git-svn tests can fail on fast machines due to a race in
Subversion: if a file is modified in the same second it was checked out
(or in for that matter), Subversion will not consider it modified. This
works around the problem by increasing the timestamp by one second
before each commit.

Subtle bugs remained on both Cygwin and Linux that caused the various
window panes to be restored in positions different than where the user
last placed them. Sergey Vlasov posed a pair of suggested fixes to this,
what is done here is slightly different. The basic fix here involves
a) explicitly remembering and restoring the sash positions for the upper
window, and b) using paneconfigure to redundantly set height and width of
other elements. This redundancy is needed as Cygwin Tcl has a nasty habit
of setting pane sizes to zero if their slaves are not configured with a
specific size, but Linux Tcl does not honor the specific size given.

When we are included as a subproject, such as how git.git carries

I've decided to use gitgui-0.5 as the format for tags in the

Because git-gui is being shipped as a subproject of the main
Git project and will often have a different lifecycle than
the main Git project, we should ship our own version number
in the release tarball rather than relying on the main Git
version file.

Git's master Makefile will invoke our own with the target
dist-version, asking us to save off our GITGUI_VERSION value
into our own version file, so that our GIT-VERSION-GEN script
can recover it at build time.

It was suggested on the mailing list that being able to use `from`
in any commit to reset the current branch is useful in some types of
importers, such as a darcs importer.

We originally did not permit resetting an existing branch with a
new `from` command during a `commit` command, but this restriction
was only to help debug the hacked up cvs2svn that Jon Smirl was
developing in parallel with git-fast-import.  It is probably more
of a problem to disallow it than to allow it.  So now we permit a
`from` during any `commit`.

While making the changes required to permit multiple `from`
commands on the same branch, I discovered we no longer needed the
last_commit field to be set to 0 during a reset, so that was removed.
(Reset was originally setting the field to 0 to signal cmd_from()
that it was OK to execute on the branch.)

While poking around in this section of fast-import I also realized
the `reset` command was not working as intended if the corresponding
`from` command was omitted (as allowed by the BNF grammar and the
code).  If `from` was omitted we cleared out the tree but we left
the tree SHA-1 and parent commit SHA-1 intact.  This is not what
the user intended in this case.  Instead they would be trying to
reset the branch to have no parent and to have no tree, making the
branch look new-born during the next commit.  We now clear these
SHA-1 values during `reset`, ensuring the branch looks new-born if
`from` does not get supplied.

New test cases for these were also added.

Most users don't need the pack boundary information that fast-import
was printing to standard output, especially if they were calling
it with --quiet.

Those users who do want this information probably want it captured
so they can go back and use it to repack the imported repository.
So dumping the boundary commits to a log file makes more sense then
printing them to standard output.
