I think "file and pipe output" is short-sighted. There are lots more cases
this is necessary including SSH sessions and emacs shell buffers, etc. And as
I pointed out there are often cases where the user may want to override the
terminal width in any case.

Earlier I suggested -- and nobody refuted -- that we should follow the
precedents of ls and man and other tools which need to find the terminal
width: Explicitly set width takes precedence always, if it's not explicitly
set then you use the ioctl, and if that fails then you use the COLUMNS
environment variable.
