- Fixed a buffer overflow problem in Curl_proxyCONNECT that could occur

  when a server responded with long headers and data.  Luckily, the buffer

  overflowed into another unused buffer, so no actual harm was done.

  Added test cases 1060 and 1061 to verify.

- Andy Tsouladze fixed runtests.pl to not attempt to execute the stunnel

  _directory_ if that happened to appear in the path!
