Given these functions:
    TTY=`tty | sed -e s:/dev/ttyp::`
    host=`hostname | tr a-z A-Z | sed -e s/.BBN.COM//`

    function pwd() {
	# This has two ESCAPEs and one BACKSPACE in it.
	echo -n "^[]lBASH@${host}(${TTY}):$PWD^[\^H"
    }

    function cd() {
	builtin cd $*;
	pwd;
    }

When I say "type pwd" my window banner gets all messed up.  I know
that being able to take your output as input is a good thing, but having
to put "|cat -v" on the end all the time is a pain.

Also, while I'm here:
    function bxmf() {
	make -k "$@" >foo 2>&1 &
	#  It doesn't seem quite right that this next line is really needed...
	: ;
    }
