Just as a point of reference, here are the output sizes of=20
postscript files produces by base 3.8k before your patch,
the current cvs version, and the current cvs version with
my patch for post.trm from the other day.

[47] wc *.ps
 107936  232574  860642 3.8j.ps
  63070  161130  566356 hbb.ps
  44492  133191  430013 hbb+eam.ps

Test command sequence was in each case:
  set term post color dash
  set output '...'
  load 'contours.dem'

I don't know if the patch to post.trm is fully safe,
but in any event this shows that there is some room
left to further optimize the postscript output over
and above the changes you made to the core routines.
