 (In [4763]) Merge r4758: Fix trailing garbage for large objects

 Fix one of those "nothing can possibly go wrong" bugs that are so
 typical of "lets just try to get this into the release" features.

 The resent addition of experimental Range: header support, broke
 a cornercase in normal content delivery.

 If an object was delivered from the backend using chunked encoding,
 and was larger than the storage segment size (default: 128k) this
 bug may bite.

 The effect of the bug is that up to storage segment worth of junk
 may be appended to the transmitted object.

 This is mostly harmless, because the Content-Length header will make
 the browser do the right thing, but certain load-balancers will
 go cross-eyed and act really weird at the TCP level, spewing
 interesting RST packets to the client.

 This bug is only in 2.1.1, not in 2.1.0.
