While the math could get a bit inconvenient I think that complexity can
entirely be hidden within the code and leave the pagelist parameter set
unchanged...  I guess I'm assuming a page editor is not going to be
specifying a given "chunk-page" -- they will just indicate somehow within
their pagelist that they want it to be "chunked" and from there on they will
click on a link...  Is that right?

That makes sense to me to have it as a PV.  I think I'd still lobby for
something related to the already-available $MatchCount or else change
$MatchCount from FmtV to FmtPV (Or add $FmtPV['$ThisMatchCount'] or the
like) -- just for consistency's sake.
