Because lots of function keys are needed by many users, we never even
consider Alt-F4 as synonymous with Quit. We capture it, and allow the user
to attach a keymap to it.

You misunderstand. It's not that telnetd or sshd would trap the HUP. They
pass it along or even generate it in the case where the connection goes
down. The problem is when some shell script in the process tree has
trapped the HUP, or when the runtime ignores it (not the case with fP).

Thanks for your comments on 'screen', too.
