7 I'm not sure how to support .children(revision) in the Arch backend
8 or the older versions of Darcs without checking out a pristine tree
9 for the revision in question. That's how we used to support
10 BugDir.duplicate_bugdir()
11 but it doesn't fit well with the new Storage system. Since I don't
12 feel strongly about tla or old Darcs support, I'm leaving that
13 functionality unimplemented.
