Comment 3 for bug 338722

I don't think its export_command (that's blank on rhel5), and PS1 is just set for the prompt

I think its something added to the screenrc for xterm

this perhaps?

# special xterm hardstatus: use the window title.
termcapinfo xterm 'hs:ts=\E]2;:fs=\007:ds=\E]2;screen\007'

i'll attach the full screenrc for you to have a look through...
