error: bogus escape: u'\\1'

[Hector Z]

(This bug refers to an older version. When it happened I ended up not reporting or writing down more details, but kept the error message anyway. Now I'm reporting them all, in batch, in the hope it still helps to fix if unfixed, or to add to regression tests.)

Cannot reproduce, also non-obvious how this can happen from code review
