Strange behaviour when open help message in commit mode amend

[deathmaz]

Hi @jreybert, i recorded the issue with asciinema - https://asciinema.org/a/9qq3wf1sz5pslilrt116sjm1t
So when i press CA you can see Commit message section with my previous commit in it. But when i pres ? to see help and then press it again to close it you can see that Commit message section is messed up. And it get's messed up even more when i press ? repeatedly.

I'm using NVIM 0.1.7.

Thank you for a nice plugin!

Indeed, this is a bug.
