I think it's hard to know how well it's going to work in advance (I was
going to try redoing all the GHC 7 merges with git, but that won't tell
us much if they would have been recorded differently in a git workflow),
so perhaps we should change only the GHC repo at first, and see how it

That way, if we decide it's worse, we haven't done a lot of work
migrating dependencies or setting up mirrors, and to roll back we only
need to migrate the new git patches into the old darcs repo.
