[Groff] cyrillic hyphenation with DVI backend

[Grigoriy A. Sitkarev]

Hello, list!

I am using groff with cyrillic.

Producing PostScript with hyphenation via -mru and -Tps options is 
smooth. Thanks to the guy who made an entry on the groff wiki concerning 
this topic.

The quality of the default PostScript output, when it comes to 
mathematics, is not very pleasent for my eye. Following some suggestions 
found in the mailing list archive, I decided to use DVI backend. After 
digging and playing a little with grodvi and devdvi settings I got the 
eye-pleasing output.

I also succeeded with adding cyrillic fonts from AMS Fonts and cmcyr 
packages. The process went smooth too, the only mess caused handcrafting 
mapping files, because cmcyr and AMS Fonts use different encoding. 
Fortunately, AMS provides a complete font charts and tweaking mapping 
files for my purposes was not very difficult.

Sadly, I couldn't get cyrillic hyphenation with DVI backend. It works 
fine for the latin and DVI, it works fine for cyrillic and PS, but it 
doesn't works for cyrillic and DVI. When I supply -mru option together 
with -Tdvi, nothing happens and hyphenation seems not to work.

I guess, choosing DVI backend somehow changes hyphenation settings.

Any suggestions will be very valuable.

Thanks in advance.
