Thanks for the refactoring! Unfortunately, this appears to lose the newlines. Although it isn't apparent at all by looking at the code that newlines are happening, it seems that every time you do snip += '...', a newline is created. I'd love to see a refactored version that maintains this aspect though.

I suspect changing snip.rv = "/**{0} */".format("".join(tags)) to snip.rv = "/**{0} */".format("\n".join(tags)) will add new lines.
