    fix: readline buggy with a color prompt
    
    When providing a color prompt and history completion via the readline module
    the prompt can be screwed up by cycling to a command longer than the
    non-displayed length of the prompt string. Unfortunatley I'm not finding a
    workaround so removing formatting from the prompt. For more information see:
