Strange prompt behavior in tcsh

[Roger Merritt]

I recently installed the port shells/tcshrc, and ever since I've been 
getting some funny output on the console whenever I change directories:

kepler:/root# echo $SHELL
/bin/tcsh
kepler:/root# cd /etc
\033]2;KEPLER - /etc\007kepler:/etc#
kepler:/etc# cd
\033]2;KEPLER - /root\007kepler:/root#
kepler:/root#

The prompt setting in .tcshrc.set is "%B%m%b:%S%/%s%# ".

Obviously it's no huge thing, but why am I seeing the \033]2...\007 string 
after 'cd'ing? Before I installed the port, my .tcshrc set the prompt to 
"%n@%m:%~%# " and I didn't get the literal string. Now it only shows on the 
first prompt after I 'cd', and after that the prompt seems to work right. 
Obviously the port sets something else, but before I start digging, has 
anyone else solved this?
