@svmehta - Thanks for this.

This is the correct change, unfortunately we're in a bit of a bind right now in that we merged #30, which means that nsqio/nsq#357 needs to be merged in order for NSQ to compile against the new go-nsq public API.

But, in nsqio/nsq#357, we no longer depend on go-nsq for the topic/channel name functions you've modified here (the NSQ repo will have its own copy).

What does this mean? We'll need another pull request on the NSQ repo side when nsqio/nsq#357 is merged, that's all.

Thanks again for your contribution.

ok will wait on you guys to merge in #357 and submit a new pull request at that time
