git-svn: dcommit --commiturl rebases against fetch url rather than against commit url

[Ingmar Vanhassel <ingmar@exherbo.org>]

Hi Eric & list,

I'm using a git-svn setup where svn-remote.svn.url is set to use
anonymouse svn, and svn-remote.svn.commiturl uses my ssh+svn:// login.

I'm using anonymous svn for fetching because this git-svn import is
shared with a few other developers, who don't have commit access, but
who do prefer to use a git-svn import over SVN, for their work. Since I
use anonsvn for the import they can continue my import.

When I dcommit to svn, git-svn happily commits the first commit. When it
tries to rebase after that it fetches from the anonsvn url, which is
synced only ever 5 or 10 minutes. Thus, it doesn't find my commit, and
it aborts, meaning I need to wait until anonsvn catches up, before being
able to do another commit.

Any suggestions on how this could be solved without reimporting with
the rewriteRoot option set?
