    # We need to surround all non-printing characters with special bash escape
    # sequences, "\[" and "\]". These sequences will tell bash that the enclosed
    # characters don't take up any space on the line, which will allow
    # word-wrapping to continue to work properly. Without them, you'll end up with
    # a nice-looking prompt that will mess up the screen if you happen to type in a
    # command that approaches the extreme right of the terminal.
