Description:

I'm using the following PS1 prompt (Debian's default for normal users):

\[\e]0;\u@\h:
\w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\
]:\[\033[01;34m\]\w\[\033[00m\]\$

...where the first block '\[\e]0;\u@\h: \w\a\]' is for setting xterm's
title, and the rest is Debian's "fancy" shell prompt.

Is there a literal newline in the prompt string? And is it in the middle
of the non-printing character block?
