No, I don't think that's right, when doing a fetch we want to store the refs somewhere, sure, but not under 'refs/heads/<branch>', perhaps 'refs/hg/fetch/<branch>', either way, the current code does not work.

Currently I'm implementing so that it would work like this for the svn helper:

$ echo capabilities | git remote-svn origin /path/to/hg/repo import refspec +refs/trunk:refs/svn/origin/trunk refspec +refs/branches/*:refs/svn/origin/*

That way we can put the refspec in the config file at clone time.

Now I've been browsing through the builtin-fetch code, and it looks like the main problem is going to be to apply this refspec at all. I'll have a more extensive look tomorrow.
