[WIP] Remove an unnecessary variable

Hi

Just looking through neovim sources again.

Again saw some weird code, thought I should sent a pull request. The code looks equivalent.
I meant the `{` and `}` on lines 446 and 452; those are preceded by a comment (that was already there), not by a condition or loop. So as far as I can see, those braces can be removed and the block can be indented one level less.
But I see how my statement was confusing, as the `if` statement hasn't been removed. The braces have been duplicated though, and that was what I meant.
