I've applied, but see below.

Technically, Reuben is not the author. He suggested the code, but he
didn't formally write the patch. You're now claiming he is the author,
but he isn't, which could be pretty bad if you somehow misunderstood
his suggestion.

In this sort of situation, I would recommend to make your self the
author, and add a:

Suggested-by: Reuben Roessler <reuben.roessler@canonical.com>

in the commit log.

That being said, since what you submitted here is what you proposed
upstream, I merged your patch as-is.

Thanks!

Thomas
