bundle: allow rev-list options to exclude annotated tags

Browse Source 
With options such as "--all --since=2.weeks.ago", annotated tags used to
be included, when they should have been excluded.  The reason is that we
heavily abuse the revision walker to determine what needs to be included
or excluded.  And the revision walker does not show tags at all (and
therefore never marks tags as uninteresting).
