This is almost as verbose as the text it directs to for detail:

    Note:
       for performance reasons, log FILE may omit duplicate changes made on
       branches and will not show deletions. To see all changes including
       duplicates and deletions, use the --removed switch.

Seems we should simply copy that text.
