[sup-talk] [CORRECTED PATCH] If we can get the terminal width, use that for WRAP_LEN.

I find that this provides a much smoother terminal experience,
especially with elinks configured to dump to the same size in hook
scripts.

At least on Linux, "stty size"'s second numerical output is the number
of columns, and if that fails somehow, sup will continue to happily
default to 80.
