Syntax highlighter does not highlight `end` when the last line in a module is a comment

[gausby]

Not the most important issue in the world, but I've noticed an issue that might be a bit hard to describe in text; I'll try anyway.

If a module has a comment on the last line the end will stop getting highlighted until the line with end has been updated. If we update the line with the comment the line with end will stop highlighting again.

Again, this is not critical. It is just a minor thing I've noticed happens that should not happen. I'll post a unit test shortly.

Fixed on master.
