    Use double brackets everywhere · 56d4dec1

    We already fixed a couple of these in previous patches - this one should
    replace all remaining uses of single brackets ("[") by double brackets.
    Also, use arithmetic evaluation instead of conditional expressions where
    appropriate and make use of "-z" and "-n" instead of comparing variables
    to empty strings.
