this is no longer a stub. the file should be sendfile.go.

shouldn't there be a doc comment here?

+        if n < 0 {
+                return io.BufferedCopy(c, r)
+        }
+        return io.BufferedCopyn(c, r, n)

why doesn't BufferedCopyn have the same if statement? then you could avoid it
here and every other call site.
