Subject: [PATCH] When requesting file data, make "Range: bytes=0-" work
 correctly

Summary: Ref T12219. Chrome can send requests with a "Range: bytes=0-" header, which just means "the whole file", but we don't respond correctly because of a `null` vs `0` issue.

Test Plan: Sent a raw `bytes=0-` request, saw a proper resonse.
