Use this rule to control the number of spaces inside brackets (``[`` and
``]``).
.. rubric:: Options
* ``min-spaces-inside`` defines the minimal number of spaces required inside
brackets.
* ``max-spaces-inside`` defines the maximal number of spaces allowed inside
brackets.
* ``min-spaces-inside-empty`` defines the minimal number of spaces required
inside empty brackets.
* ``max-spaces-inside-empty`` defines the maximal number of spaces allowed
inside empty brackets.
.. rubric:: Examples
