	Setting environment variables doesn't change the behavior of your
terminal window. As best I could tell, it is the local host which decides
when output wraps - the remote host just sends it raw, and the local terminal
decides when there's too much, so inserts a newline.
	Setting  columns would be an option in the stty() routine, but
'columns' isn't part of the POSIX terminal spec, so isn't supported by stty(),
which uses the POSIX library for terminal handling. Thus the ugly kludge.
	Net::Telnet may save you here because it doesn't filter through a
terminal at all. Come to think of it, you could probably just use
open2 to start telnet without a terminal, then use Expect on the filehandles
open2 returns.

	Anyway, that's probably as much talk about globs and terminals that
anyone can handle this week. :-)
