narrow: only walk files within narrowspec also for committed revisions
Narrow has been walking only paths matching the narrowspec when
walking the working copy. We have not done the same filtering when
walking committed revisions (e.g. "hg files -r "), which seems a
little odd. Let's make it consistent.

Just run the fuzzers for five seconds each to verify it works at all.
