How about this:

	mesg () {
		command mesg $*
		setopt localoptions nullglob
		local tty
		tty=( ${~TTY:s/dev/de[v]/}(I) )
		case $tty in
			$TTY)
				TALK=
			;;
			'')
				TALK="<notalk> "
			;;
		esac
	}

Question:  Is there any easier way to get the (I) glob qualifier applied
to the value of $TTY ?  I had to invent that de[v] trick just to force
there to be a pattern somewhere in the string.
