I looked into it a bit. PfEd is the foundry name. "PfEd" is short for 
"PfaEdit", the former name of FontForge. The string "PfEd" appears in 
the binary file /usr/share/fonts/dejavu/DejaVuSansMono.ttf and comes 
from the line "OS2Vendor: 'PfEd'" in 
dejavu-fonts-2.35/src/DejaVuSansMono.sfd. Perhaps other font generators, 
or older versions of FontForge, or older versions of this font, don't 
fill in the foundry field, which would explain why you're seeing 
"unknown" rather than "PfEd". See:

http://sourceforge.net/p/fontforge/git/ci/master/tree/fontforge/PfEd.h
https://raw.githubusercontent.com/dejavu-fonts/dejavu-fonts/master/src/DejaVuSansMono.sfd

I doubt whether this level of trivia needs to be in the manual, but 
figured that if other people were curious about that 'PfEd' they might 
appreciate the info.
