Hi, I recently got a copy of John Gilmore's paper:
http://mcvoy.com/lm/papers/porting-berkeley.ms and if I do groff -ms -Tpdf porting-berkeley.ms > porting-broken.pdf the pdf is not readable by firefox. I get the popup that says "This PDF might not be displayed properly". That file is there at http://mcvoy.com/lm/papers/porting-broken.pdf If I do groff -ms porting-berkeley.ms > PS ps2pdf PS porting-berkeley.pdf I get: http://mcvoy.com/lm/papers/porting-berkeley.pdf which displays fine. This is on xubuntu (debian stretch/sid), groff version 1.22.3., firefox 76.0.1 (64 bit), x86_64. Let me know if I can provide any more info. --lm
