It adds convenience. It makes it easier to set a pagelist chunk. You
just need to calculate the start value, and supply the count value.
So it simplifies the math involved.
It will still not be easy to construct a dynamic link navigation
like (Go to page 1 2 3 ....)
within a custom template. But it just may be possible.
For a general breakpagelist recipe I think we still require an
additional pagelist to supply the pagelist count, which the script
will use to calculate the range parameters for the actual pagelist
(the one which produces formatted output).

I suggested $FmtPV['$PageListCount'] = $PageListCount;
I am not picky on the name either, but I thought we need a PV for use
in a pagelist template.
Other custom FPLFormat functions can use count($matches) to
get the count.
