Double wildcard paths like collection** on change events (missing return value)

[treet]

I can't get hooks like store.allow('change', 'collection**') or store.allow('change', 'collection.**') to work, any validations added on such paths will never trigger. store.allow('all', 'collection**') still triggers fine, which I think has to do with _allow_all checking manually for those kind of paths. Are these patterns not available for change events? Is the missing return value a bug or was it intended?

How can I capture all changes under a specific collection?

(Edit: I just realised these changes are wrong, relativePath should perhaps return something like [null].concat(relativeSegments)?)
