[Groff] character class patch

[Daiki Ueno]

Hi,

Sorry if it sounds pestering.

In this summer I was trying to finish the character class patch by Brian
M. Carlson and Colin Watson, for better Japanese rendering.  At that
time it basically worked, but since then I have fixed some "TODO" items
marked in the original patch.  The current patches are at:

http://ueno.fedorapeople.org/groff/
0001-Import-Colin-Watson-s-charclass-branch-with-minor-fi.patch
0002-Use-wcwidth-to-determine-glyph-width.patch

As a Japanese user, I'm hoping that this feature will be included in the
upstream.  Anyway, any comments or suggestions would be appreciated.

P.S.  Now we are going to start testing it in Fedora Rawhide (the
development branch for the next Fedora release) since we don't see any
concern:
