The attached two pdfs are for an 8x3 inch and a 4x1.5 dashed ellipses, i.e.
one is half the size of the other. One looks lovely and one a mess. Both
produced with this command:-

test-groff -Tpdf -ms -p -P-l file.trf > file.pdf

Changing the output device to -Tps does not make any difference, so I think
this indicates the problem lies in pic, possible variable overflow?
