4 lines produced instead of 1 when extending double-slash comments

Hi, Thanks for the great plugin. Since the last update (I'm now on 0.13.7), when I write a double-slash comment and press enter it produces 4 new comment lines instead of 1.

Could this be a duplicate of #202?

It certainly looks similar, although everyone in that thread seems to be getting double new lines whereas I'm getting quadruple. Send likely there is a common cause which, according to comments in the other thread, is related to the update process.
