OK. I'll type the gremlin file format and send it one of these

Just delete it from the man page. If I come out with an idea it
will be handy to have the code already written for a flag.

You're right. The original man page says:

"Set the thickness of gremlin's narrow (medium or thick) lines
to N. The default is 1 (3 and 5) pixels."

So having an integer as a scaling factor makes sense only if
you're magnifying the minimum quantum (pixels), but now that we
are using points, we can switch it to a floating point number
(patch sent). The man page should also be modified to
something like:

narrow N
   (medium, or thick) Sets the thickness of gremlin's narrow
   (medium or thick) lines to N * BASE_THICKNESS. The default for N
   is 1 (3 and 5). BASE_THICKNESS is 0.15p that can be modified at
   compile time
