There was a bug in dcommit (and commit-diff) which caused deltas
to be generated against the latest version of the changed file
in a repository, and not the revision we are diffing (the tree)
against locally.
This bug can cause recent changes to the svn repository to be
silently clobbered by git-svn if our repository is out-of-date.
Thanks to Steven Grimm for noticing the bug.
The (few) people using the commit-diff command are now required
to use the -r/--revision argument. dcommit usage is unchanged.

-r (recursive) is passed by default, since users usually want
it, and accepting it causes difficulty with the -r<revision>
option used by svn users. A --non-recursive switch has been
added to disable this.
Of course, --summary, --raw, -p and any other git-log options

This bugfix applies to users of the svn command-line client only.
We no longer muck with newlines when killing keyword expansion.
This tended to generate unintended diffs in commits because svn
revert -R would destroy the manual EOL changes we were doing. Of
course, we didn't need the EOL munging in the first place, as
svn seems to do it for us even in the text-base files.
Now we set the mtime and atime the files changed by keyword
expansion killing to avoid triggering a change on svn revert,

--follow-parent:
This is especially helpful when we're tracking a directory
that has been moved around within the repository, or if we
started tracking a branch and never tracked the trunk it was
descended from.
This relies on the SVN::* libraries to work. We can't
reliably parse path info from the svn command-line client
without relying on XML, so it's better just to have the SVN::*
libs installed.
This also removes oldvalue verification when calling update-ref
In SVN, branches can be deleted, and then recreated under the
same path as the original one with different ancestry
information, causing parent information to be mismatched /
misordered.
Also force the current ref, if existing, to be a parent,
regardless of whether or not it was specified.
--no-metadata:
This gets rid of the git-svn-id: lines at the end of every commit.
With this, you lose the ability to use the rebuild command. If
you ever lose your .git/svn/git-svn/.rev_db file, you won't be
able to fetch again, either. This is fine for one-shot imports.
Also fix some issues with multi-fetch --follow-parent that were
exposed while testing this. Additionally, repack checking is
simplified greatly.

Tested on a plain Ubuntu Hoary installation
using subversion 1.1.1-2ubuntu3
1.1.x issues I had to deal with:
* Avoid the noisy command-line client compatibility check if we
use the libraries.
* get_log() arguments differ (now using a nice wrapper from
Junio's suggestion)
* get_file() is picky about what kind of file handles it gets,
so I ended up redirecting STDOUT. I'm probably overflushing
my file handles, but that's the safest thing to do...
* BDB kept segfaulting on me during tests, so svnadmin will use FSFS
whenever we can.
* If somebody used an expanded CVS $Id$ line inside a file, then
propsetting it to use svn:keywords will cause the original CVS
$Id$ to be retained when asked for the original file. As far as
I can see, this is a server-side issue. We won't care in the
test anymore, as long as it's not expanded by SVN, a static
CVS $Id$ line is fine.
While we're at making ourselves more compatible, avoid grep
along with the -q flag, which is GNU-specific. (grep avoidance

This means we no longer have to deal with having bloated SVN
working copies around and we get a nice performance increase as
well because we don't have to exec the SVN binary and start a
new server connection each time.
Of course we have to manually manage memory with SVN::Pool
whenever we can, and hack around cases where SVN just eats
memory despite pools (I blame Perl, too). I would like to
keep memory usage as stable as possible during long fetch/commit
processes since I still use computers with only 256-512M RAM.
commit should always be faster with the SVN library code. The
SVN::Delta interface is leaky (or I'm not using it with pools
correctly), so I'm forking on every commit, but that doesn't
seem to hurt performance too much (at least on normal Unix/Linux
systems where fork() is pretty cheap).
fetch should be faster in most common cases, but probably not all.
fetches will be faster where client/server delta generation is
the bottleneck and not bandwidth. Of course, full-files are
generated server-side via deltas, too. Full files are always
transferred when they're updated, just like git-svnimport and
unlike command-line svn. I'm also hacking around memory leaks
(see comments) here by using some more forks.
I've tested fetch with http://, https://, file://, and svn://
repositories, so we should be reasonably covered in terms of
error handling for fetching.
Of course, we'll keep plain command-line svn compatibility as a
fallback for people running SVN 1.1 (I'm looking into library
support for 1.1.x SVN, too). If you want to force command-line
SVN usage, set GIT_SVN_NO_LIB=1 in your environment.
We also require two simultaneous connections (just like
git-svnimport), but this shouldn't be a problem for most
servers.
Less important commands:
show-ignore is slower because it requires repository
access, but -r/--revision <num> can be specified.

New commands:
graft-branches - The most interesting command of the bunch. It
detects branches in SVN via various techniques (currently
regexes and file copies). It can be later extended to handle
svk and other properties people may use to track merges in svk.
Basically, merge tracking is not standardized at all in the SVN
world, and git grafts are perfect for dealing with this
situation.
Existing branch support (via tree matches) is only handled at
fetch time.
The following tow were originally implemented as shell scripts
several months ago, but I just decided to streamline things a
bit and added them to the main script.
multi-init - supports git-svnimport-like command-line syntax for
importing repositories that are layed out as recommended by the
SVN folks. This is a bit more tolerant than the git-svnimport
command-line syntax and doesn't require the user to figure out
where the repository URL ends and where the repository path
begins.
multi-fetch - runs fetch on all known SVN branches we're
tracking. This will NOT discover new branches (unlike
git-svnimport), so multi-init will need to be re-run (it's
idempotent).
Consider these three to be auxilliary commands (like
show-ignore, and rebuild) so their behavior won't receive as
much testing or scrutiny as the core commands (fetch and
commit).
