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.
