Re: [PATCH v2 2/5] Update documentation for new directory and status logic

>>> +If this is set, files and directories that explicity match an ignore
>>> +pattern are reported. Implicity ignored directories (directories that
>>> +do not match an ignore pattern, but whose contents are all ignored)
>>> +are not reported, instead all of the contents are reported.
