Use double brackets everywhere

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.
