After an unreasonable amount of thrashing around, I finally discovered what was causing my pain: the set-url bit of sync-all doesn't work. Look at this. See the red below. The sub-modules don't have a ".git" suffix. The other packages do. Geoff thinks that the sync-all script has code for deciding whether to add the ".git" or not, but the code was omitted when adding the sub-module stuff. Result: in subsequent stuff, git looks in a darcs repo, with consequent terribly confusing results. Ian could you fix please?
