This enables git-svn.perl to read multiple 'branches' and 'tags' entries in
svn-remote config sections. The init and clone subcommands also support
multiple --branches and --tags arguments.
The branch (and tag) subcommand gets a new argument: --destination (or -d).
This argument is required if there are multiple branches (or tags) entries
configured for the remote Subversion repository. The argument's value
specifies which branch (or tag) path to use to create the branch (or tag).
The specified value must match the left side (without wildcards) of one of
the branches (or tags) refspecs in the svn-remote's config.

I got carried away making unit tests and went and implemented most of this...
I'm fairly happy with this, except for the way the branch subcommand matches
refspecs. The patch does a simple string comparison, but it'd be better to do
an actual glob. I just couldn't track down the right function for that, so I
left it as a strcmp and hope that a gitizen can tell me how to glob here.
(ps. I'm trying a new way to send patches -- apologies if it's mangled!)
