net/http: Range request edge case

[gopherbot]

by jed@fastly.com:

There's currently a bug with ServeContent and FileServer when handling Range requests.

Given a file of size N, a request for "Range: bytes=N-*" should return a 416. 
However, currently, it returns 206, a body of 0 bytes, and the illegal Content-Range of
"bytes N-(N-1)/N".

Can you please consult for RFC 7233 instead of RFC 2616? I'm not sure how much impact will we have on http://tools.ietf.org/html/rfc7233#appendix-B.

So far as I can reason, the updated RFC doesn't change what should be done in the case this CL addresses. But I will update the language quoted in the change description.
