Alas, the example I just sent out confuses bash too easily.
The problem is most likely that the length of the string
is longer than the actual visible prompt string.
So simple commands work fine, but (say) file-name completion
loses big.

In fact, I got the following output:
free: Called with already freed block argument

Tell bfox@ai.mit.edu to fix this someday.

	--Per
P.S.
One solution is to have "normal" strings in PS1,
and then alias cd,pushd, etc to have the side effect of
changing the title bar. This works reasonably well in tcsh,
but I haven't tried it for bash.

It would also help if readline (?) could be made more robust.
This may be hard for arbitrary control sequences, but one
could have a convention that when calculating the length of
a prompt string, only count characters after a '\r' or '\n'.
Then one could place a '\r' after the "invisible" part of the prompt.

Another solution is to do something like tcsh's precmd alias,
which is automatically executed before each prompt.
The "precmd" could be responsible for setting the title bar.

This is a Bash bug report.  Bash maintainers should be getting this report.
If this mail has bounced, for right now please send it to:

	bfox@ai.mit.edu

since he is the current maintainer of this version of the shell.

This is /usr/local/bin/bash (invoked as `/private/usr/local/emacs/info/bash'), version 1.03.109, on host wslt03.pa.dec.com, used by bothner.
This shell is interactive, and it is not a login shell.

The host is a SONY running Bsd.

The current environment is:

{ TERMNAME="$*"; if [ "$TERM" = "xterm" ] ; then
  echo -n "]1;${TERMNAME}"
