My apologies.  I didn't mean to patronize you in particular, just
anyone that thinks that "runs on my redhat box" means "portable".

If that's not you, and I came across as patronizing you, I am sorry.

I have simply been bitten too many times by people writing software (or
dispensing advice) that have that attitude.  You may not think that
way; I don't know.

He was clearly using "contemporary Berkeley or Linux platforms" as
examples to illustrate his point, which was that "the COLUMNS
environment variable isn't universally available on UNIX platforms".
He was correct in that, even if COLUMNS is available on Redhat.

There's not much point in continuting this in any case, as a portable
solution seems to already have been supplied.
