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