Well, as far as it takes.  Actually, the search should be fairly well constrained.  After checking that the entries under a particular path aren't a copy of the trunk, each entry can only represent either a branch that git-svn already knows about, or a new branch.

Not sure what you mean there.  Can you come up with an example of this?

Turning the branch refspecs into true regular expressions sounds like a good idea to me, and would probably be easier to implement than the trunk-detection stuff I proposed.  Though there'd have to be a way to stay compatible with or upgrade the current non-regex refspecs.

All of git-svn is already a hack for dealing with SVN.  :)  I'm sure a patch for this would be welcome.
