   4   * In Git, there appears to be no way to send a message which will be output
   5   * by `git clone http://...`, although the response code is visible.
   6   *
   7   * In Mercurial, the HTTP status response message is printed to the console, so
   8   * we send human-readable text there.
   9   *
  10   * In Subversion, we can get it to print a custom message if we send an
  11   * invalid/unknown response code, although the output is ugly and difficult
  12   * to read. For known codes like 404, it prints a canned message.
  13   *
  14   * All VCS binaries ignore the response body; we include it only for
  15   * completeness.
