Follow-up Comment #2:

Doug was good enough to respond to me via email since Savannah seems to have
deployed a CAPTCHA against non-logged-in users that only machine intelligences
can penetrate.


The complaint identifies an infelicitous feature, but technically not
a bug. The spacing of dots scales with other graphics. The spacing is
settable.

The particular example,

     line from 0 to 100 dotted

should give full coordinates for the points:

     line from 0,0 to 100,0 dotted

You can set the spacing between dots. This will place them 5 units apart:

      line from 0,0 to 100,0 dotted 5

The spacing of dashes can be set the same way.
The length of dashes is set by the dashwid variable.

I commend /usr/share/doc/groff/pic.ps as an eminently
readable reference, the presence of which is not widely
known.


With that clue in hand, I am able to reproduce the problem.  I think updating
the documentation might be a sufficient remedy.

Thanks, Doug!
