Thank you for the patch.

This is ok.

This is peculiar because both the original code and the new code have
backslashes in the "set" command -- gdb_prompt is actually a regexp, not
just a plain string.  But, it works anyhow, I guess something along the
way is ignoring the "\".  So, although it is weird, your patch doesn't
make it any worse.
