Is it the entry in the page history (action=diff) that you want to
change, or the entry on RecentChanges pages? If the first, you'll need
to prepend a function to the $EditFunctions array (looped through when
a page is saved) that'll change the contents of the new page's "csum"
and "csum:$Now" fields to whatever you want. If the latter, you should
define your own $RecentChangesFmt array.

Alternatively, you could do the replacement using Javascript when the
edit form is submitted.
