[gropdf] Unable to render ellipse with dashed/dotted atribute

[Morten Bo Johansen]

Trying to convert to pdf from this groff source:

   .PS
   elipse dotted
   .PE

with the command:

   groff -Tpdf -p 

yields a broken/empty pdf. Opening it in e.g. zathura gives
this error message:

  format error: cannot recognize version marker
  warning: trying to repair broken xref
  warning: repairing PDF document

This also applies to circles.

Trying to convert to pdf from this groff source:

   .PS
   elipse dashed width 6 height 3
   .PE
  
outputs a dashed ellipse with two unwanted vertical lines
running through it. It only happens if width >= 6. With e.g.
width = 5, it renders okay.

With groff -Tps, there is no problem.

~/ % groff --version
GNU groff version 1.23.0
