[Groff] man-page fixes

[Axel Kielhorn]

Hi!

I'm currently adding a section about further literature to my short 
guide.
While reading the man-pages I stumbled over a few things:

groff_char.man the Latin-1 (ISO-8859-1) code.

groff.man (7) linkt to http://cm.bell-labs.com/cm/cs/54.ps but the 
actual file is at
http://cm.bell-labs.com/cm/cs/cstr/54.ps.gz (Which is actually a ps 
file, unless my browser ungziped it on the fly.)

Do you want patches?
If yes, which format?

Axel
