I don't see that behavior here on Ubuntu 7.10:

boot home lib opt sbin u win
$ ls --version
ls (GNU coreutils) 5.97
Well, it's *certainly* gonna ignore "COLUMNNS".

I'm having trouble seeing the relevance, either way. First many shells
don't set $COLUMNS at all (readline does it for psql). And most shells
that set $COLUMNS don't export it. So most people get different output
from:
# ls -C
# ls -C | cat
Unless they are in the habit of doing:
# COLUMNS=$COLUMNS ls -C |cat
I think it's too weird to default pipes to whatever the terminal width
happens to be. So that leaves you with an explicit command to set the
width for pipes.
