This does more than just set your prompt and colour it.
It also sets the xterm title to "user <at> host: pwd".

man console_codes:

   ESC ] 2 ; txt ST        Set window title to txt

This is not an ANSI colour escape sequence and so is not handled by
ansi-color. It's not appropriate to use such a PS1 setting on something
that is not an xterm. For example, it also messes up on the Linux
console.

My prompt is rendered with garbage like this:

It happens with emacs -Q

Steps to reproduce:

M-x shell RET
M-x load-library RET ansi-color RET
M-x ansi-color-for-comint-on RET
