What steps will reproduce the problem?
1. http://play.golang.org/p/eYUX4vZzNB 

What is the expected output?

"GET / HTTP/1.1\r\nheader:foo\r\n\r\n" <nil>
"GET / HTTP/1.1\r\nheader:foo\r\n" unexpected EOF
"" EOF

What do you see instead?

"GET / HTTP/1.1\r\nheader:foo\r\n\r\n" <nil>
"GET / HTTP/1.1\r\nheader:foo\r\n" EOF
"" unexpected EOF

Please provide any additional information below.

I expect ReadRequest to return io.ErrUnexpectedEOF when the stream ends in the middle of
a request and io.EOF when the stream ends at a request boundary.  The opposite errors
are returned.
