Use this rule to control the number of spaces before and after commas (``,``).

|
.. rubric:: Options

|
|
* ``max-spaces-before`` defines the maximal number of spaces allowed before

commas (use ``-1`` to disable).
|
|
* ``min-spaces-after`` defines the minimal number of spaces required after
|
|
commas.
|
|
* ``max-spaces-after`` defines the maximal number of spaces allowed after
