[grammar] its not possible to specify no regex for comments or eol_comments #303

Closed apalala closed 10 months ago

In this case // is a valid regex that matches nothing. We should be able to filter for False, or None, or ().

This issue needs a unit test. Also, make sure that the default for comments in tokenizers is None.

Checked the above, and inform.ParserConfig.comments_re defaults to the value of the grammar for TatSu grammars.
