Oh, it appears I've completely misunderstood what you were trying to do!
Sorry.
I haven't been able to replicate your problems with gnome
terminal, my version is 2.14.2.
I don't get the example you provided:
http://lists.gnu.org/archive/html/screen-users/2007-07/msg00009.html
> """
> address@hidden:~$ echo $PROMPT_COMMAND
> echo -ne "address@hidden:${PWD/#$HOME/~}\033\\
> address@hidden:${PWD/$HOME/~}\033\\"
> """
shouldn't there be an '\033k' somewhere to start the escape
sequence off?
I tried defining a function to do the escaping and called it
from PROMPT_COMMAND:
"""
harry8~> function settitle() { echo -n -e '\033k'"$@"'\033\134'; }
harry8~> PROMPT_COMMAND='settitle address@hidden:${PWD/$HOME/\~}'
"""
which worked for me at least. ;-)
cheers

I got it working with some help from do nothings suggestion. I really
liked his suggestion of using a function to the escaping, it really
clears up what is going on. Then I simply removed "134". I had found
the original code I got this from which stated they were using "\134"
for "\" because of a bug in an earlier bash.
I had tried a similar thing before, but with everything defined
directly in the PROMPT_COMMAND line I ended up with "\$" which didn't
work and "\\$" didn't parse right.
Thanks donothing!
Now do you know what I might need to do to get those single tick
marks? (Actually I think they are forward tick marks that I have
problems with.) :)
