This is just plain wrong in any bash version. Any part of the prompt that
does not cause the cursor to change position needs to be protected inside
\[ \]. Thus, the sequence from ESC to BEL on line 2 of your script should
be inside \[ \].
Using a CR (^M) probably screws things up as well. I don't even know why
you have that in there. If you want to ensure the prompt always starts
on a new line, use a newline instead of a CR, which will presumably
start to overwrite the last line of the previous command's output, if
that output doesn't end with a newline of its own. I would not expect
this to be the desired behavior.
In any case, you have a working prompt in your original email, so you
could just stick with that one.
