When I go into F5 mode viewing myself from the front, a line of chunks behind the one my character's in doesn't render. As I move my character, the line of chunks unrendered moves.

(sorry if this is a duplicate, but I couldn't find it when I did several searches)

What I expected to happen was...:
That the chunks behind my character would render when in F5 mode that allows viewing my character from the front.

What actually happened was...:
A line of chunks behind my character unrenders even when in F5 mode.

Steps to Reproduce:
1. Open snapshot 14w30b
2. Open a world
3. Press F5 until you're viewing your character from the front
4. Chunks in a line behind your character are unrendered
