 Yes, I understand that.  My concern is that less(1) should not attempt
 to manipulate the terminal if it doesn't have a controlling terminal.
 
 I agree that timeout(1) should be better about setting things up, but
 that's a separate issue.  As Matthew noted, there appear to be two
 distinct bugs here.  Should we split this?
