Two trivial questions

[Peter Schaffter]

Is there a correct pronunciation of groff?  I've been checking
out YouTube videos on groff.  The uploaders all say "groff" (one
syllable, like "gruff").  I say "g-roff" (to match t-roff and
n-roff).

Second question, maybe not so trivial.  Is it acceptable to use a
comma for decimal fractions that are arguments to requests and
macros (say .ps 12,5 instead of .ps 12.5) if a user's locale
supports it?
