I've deprecated the names 'multi-fetch' and 'multi-init'; however the
functionality they support have been integrated into the 'init' and
'fetch' commands.

Wildcards for branches and tags are now supported.  (multi-)init -b/-t will
create something like this now:

[svn-remote "svn"]
	url = http://server.org/svn
	branches = branches/*/project-a:refs/remotes/*
	tags = tags/*/project-a:refs/remotes/tags/*
	trunk = trunk/project-a:refs/remotes/trunk

I've made --follow-parent the default now.  --no-follow-parent reverts
back to the old default behavior.

This is in, as is the analogous functionality for svnsync.  Please note
that these features do add some complexity to how dcommit works which
I haven't explored much of.  Perhaps Sam knows better what to do with
it.

New changes pushed out.

After a few days of dogfooding and nothing breaking; I'd say it's ready
for merging into mainline git.  One last minute change I made while
writing this announcement was supporting invocations from
subdirectories.

There's a lot of changes in here; so I don't think I'll bomb the
mailing list with 113 patches.  Feel free to fetch or clone from
the repositories given above.
