Description:
    Under cygwin with the following prompt:
        PS1="\[\033[106m\]\u@\h\[\033[m\]:\[\033[103m\]\w\[\033[m\]:\! \$ "
    Inside xterm, the prompt would become:
        joe@machine:~:999 $ $
    Notes the double $ signs. (Notes joe and machine are displayed in colors correctly.)
    The same PS1 works well on Linux boxes.
    So looks like a cygwin specific problem.
    Occasionally, the prompt can be displayed correctly (e.g. after pressing Tab for autocompletion).
    But then the command line would be displayed incorrectly, looks like this:
        joe@machine:~:999 $ $ ls t[TAB]
        test/ tmp/
        joe@machine:~:999 $ ls tt
    Notes the second prompt is correct now but the last 't' character becomes 'tt'.

Repeat-By:
    Simply set:
        PS1="\[\033[106m\]\u@\h\[\033[m\]:\[\033[103m\]\w\[\033[m\]:\! \$ "
    under a cygwin xterm.
