As a page editor or user, I would expect to be able to say "count=20"
and have the pagelist chunking give me 20 results per page.
I wouldn't expect that I'd have to adjust the start/end points
on each subsequent request.

Or, to look at it another way, Google uses a "start=" parameter
to indicate where the next 'group' of results are to begin.
I'd like the same for PmWiki.

$MatchCount exists primarily for historical and backwards compatibility
reasons (from a time before we had page variables or template 
substitutions) -- I'd prefer to be moving away from the $FmtV and
not adding more of them or making them "more official".
