BUG: hp2ps: MARKs wrongly placed unless x-axis starts at zero

Hi,

I found a bug in hp2ps:  if you use MARKs, it seems to assume the x-axis
starts at zero.  So if your x-axis starts at, say, 5, then all the marks
get shifted to the right by 5 x-units.  See attached file for an example.

This is with GHC 5.04.2, but judging from CVS most of hp2ps hasn't been
touched in 7 years, so I imagine it hasn't been fixed since :)

Thanks.
