[Groff] Negative patch (removed round_width)

[Gaius Mulley]

Hi Werner,

as requested here is a patch to remove the unnecessary round_width
from all devices except grohtml. Hopefully this is a pleasant negative
line count patch!

I created the patch against the cvs of this morning and built it on
pure64 debian unstable - and it flew :-) 43sec to build (real time). I
remember when groff took 10 minutes to build on a 350 Mhz Pentium II
(without the -O2 to save time..).  Anyway enough reminiscences, here
is the patch,

Gaius
