The example has the following text [1] """ # (*) Actually, each path will select just one group. Thus, it is possible # that one group will match against all paths, while another group matches # none of the paths, even though its for_paths would have selected some of # the paths in the commit. """
It's not clear what this means. AFAICT, multiple groups *can* match a single path. But maybe it means something else? Sebb [1] https://github.com/apache/subversion/blob/91748f254bd2710f9df04b765d11276ab7c10ce4/tools/hook-scripts/mailer/mailer.conf.example#L70-L73
