[PATCH] Fix for coverity scan issue 740413

Hi,
  there seems to be a buffer overrun in the Scoutcast related test in
testHttpReply.
The attached patch may address it - it's unclear to me whether the
cstring-termination \0 should be appended to the MemBuf - I assume so as
the test is not crashing, but you never know.
Unless the trailing garbage to the input is intentional, if so I'll mark
the bug as intentional in coverity.

Thanks
