Commenting the last line of a file fails + empty lines

[plutonium-239]

The comment command fails when on the last line of a file. (video)

Also, you can't toggle comment on an empty line (which is a feature I like in sublime). Does that warrant its own issue? I figured to mention it here since these are closely related.
