[Groff] Error messages when including eps file

[Robert D. Goulding]

This has been outstanding for a while - is there a simple fix for it?
When including any .eps file produced by dvips, grops emits an error
message for every %%BeginProcSet line.  So, the attached .eps file gives
the errors:

grops:herigone1.eps:11: missing argument
grops:herigone1.eps:57: missing argument
grops:herigone1.eps:77: missing argument
grops:herigone1.eps:135: missing argument
grops:herigone1.eps:363: missing argument
grops:herigone1.eps:498: missing argument
grops:herigone1.eps:619: missing argument
grops:herigone1.eps:635: missing argument
