[Groff] how to change the number of columns for utf8 device

[zhangweiwu]

Hello. TFM has been very long, I read it through only once and later
come to it only to do the search for keyword. This time this method
doesn't work, I could not find out how to define the number of columns
(number of characters in a row) for utf8 output device.

And google fail me again, it always produce information related to tbl
which has "real" columns.

Besides, is it possible to do 2-column page layout with utf8 device?
Like this one (read it on wide screen, sorry but this is the only thing
close I can produce:

address@hidden:Readings$ groff -ms -Kutf8 -Tutf8 < study.roff | head -n 190 | 
tail -n 50 |awk 'FNR > 25 {print l[FNR-25] " | " $0;} FNR <=25 {l[FNR] = $0;}'
