[Groff] periodcentered vs. dotmath

[Werner LEMBERG]

Dear friends,


Is latin-1 glyph 183's PS name `periodcentered' or `dotmath'?  There
is an interesting ambiguity between these two characters;
additionally, these glyphs are not unified in Unicode.  For example,
you can't access Times-Roman's glyph 183 with a groff glyph name; you
have to use char183 (or \C) which is unfortunate.

I will add a new glyph name `pc' which represents periodcentered (and
retain `md' -- middle dot -- for dotmath).

Comments?
