I'd like to mention - although this might not be a full
answer to the OP's initial question - that this is
similarly done when converting manual pages to PS or
PDF output for better printing.
[ "$1" != "" ] && zcat `man -w $1` | \
groff -Tps -dpaper=a4 -P-pa4 -mandoc | ps2pdf - $1.pdf
This would cause groff to format for A4 paper width.
It's fully possible that a similar approach can be used
for requesting a specific terminal width given in
characters, rather than inches or centimeters (from
a predefined value).
