3.16.57-rc1 review patch. If anyone has any objections, please let me know.

commit 134aecbc25fd77645baaea5467b2a7ed8e9d1ea7 upstream.
Because this is a post-op instead of a pre-op, then it means we check if knl_buffer[-1] is a space. It doesn't really hurt anything, but it causes a static checker warning so let's fix it.
