Because he doesn't want to lose the history for pages that have *not*
changed a lot.  If one has a blanket "$DiffKeepDays" value, say if one
had a $DiffKeepDays value of 50, then a page that was last changed two
months ago would lose all of its history.  The problem is that there
appears to be a mixture of some pages that are changing a lot, and other
pages that aren't.

Thus, what is wanted is some way of "trimming" the history only when the
history becomes unmanageable, and keeping it otherwise.
