Hi folks,

I am implementing a module that mimics a MQTT broker. For this I am
transforming topics passed to the register function so I can run
string.match() on incoming messages.

Right now I am stuck how to correctly handle the multilevel wildcard:

Suppose the topic filter "/sport/#" and these published message topics:

Only the first three are allowed to match, so "/sport.*" is not an
option as that would match the forth one as well. On the other hand
"/sport/.*" would not match the first one.

Any ideas?
