Fwd: vcs-svn and friends

Hi,

Thanks to the work of Dmitry, we now have a simple front-end that exercises the yet unmerged changes to vcs-svn that Jonathan and I authored a few months ago. I think there's still some work to be done before we can bless an integrated branch for inclusion. I'd like to bring attention to just how far we have diverged; see the email below.

There are a lot of svn-fe tests failing on my integration branch. One upside is that gph/master..db/svn-fe-pu only contains relevant commits. I think a little more polish is needed before we can suggest a pull to jch. In particular, I think we should include remote-svn-alpha and the test should work out of the box.
