Well, I found another use for it that I can live with.  I wrote a routine
to produce a table that contains an arbitrary number of lines.  It is
invoked with:

   mark [(stuff) (stuff) ...]
        [(more stuff) ... ]
        ...
        [(last stuff) ...] functioncall

I use counttomark to find out how many lines are in the table and do a
cleartomark at the end just for completeness.
