Bash on windows is ugly anyways ;)

I think git-svn takes care of most of the branching problem on a local
basis. Where it fall down, IMHO, is in testing a branch on the builtbots and
sharing a branch among two or three people.

I tend to agree that changing the VCS shouldn't be the first priority. It
sounds like tracking the tickets and svn changes relevant to particular
tagged releases might be where the effort should go.
