I got this when trying to copy this gist on vim: <https://gist.github.com/w0ng/3278077>

![enter image description here](https://i.stack.imgur.com/MnvS9.png)

I notice the same behaviour everywhere: If I paste something that includes a comment, everything that follows the comment is pasted commented.

Maybe it has something to do with the fact that if I write a comment on insert mode and press enter, the following line automatically appends a comment.

How can I get rid of this behaviour?
