I move my windows around and even resize them sometimes. Sometimes
ksh catches on, but a lot of the time it doesn't. The problem is if
I'm running an editor like vi (kinda common reason why I'd want to
resize the terminal), sigwinch doesn't get to ksh. Then when I exit
the editor, command line editing is all messed.
Fix is simple. Pretend we got a sigwinch whenever we do the regular
mailcheck/jobs notify stuff. Then the edit code will check the
current status.
