Thanks! :-) :-)

No, afaik there is no other way to limit the displayed diffs per page, except 
deleting them with ExpireDiffs.

I submitted this patch more than a year ago and it is cool that it still 
works. Actually, the system file pagerev.php has not changed since then, so 
the patch is still up-to-date.

I wanted this change, because I believe *all* page history should be kept on a 
public wiki, and I am also influenced by my experience with Wikipedia. see 
also the section:
   4. Why provide full version history?     in
   http://www.usemod.com/cgi-bin/mb.pl?VersionHistory

And, when a page has a long history, it is sometimes hard /slow for the 
browser to display it. A long page with a couple of vandal defacements and 
reverts, quadruples the length of the history page.

The change is small and changes nothing to the current behaviour of PmWiki, 
only wikis with a setting $DiffCountPerPage=Number in config.php can benefit 
from it.

Thanks,
Petko
