Any sequence of non-printable characters should be enclosed in '\['..'\]'
for bash to not count it towards the current length of the line.

'\e]0;' will set the window title to the string that follows it (up to a
'\a', so that's the terminator). So, the above should set the window
title to the current working directory, and the prompt will be displayed
as "C09-272-A:". If you wanted the current working directory displayed in
the prompt, you could use "\[\e[01;33m\]C09-272-A:\w:\[\e[0m\]" instead.
