Daniel Stenberg (9 Mar 2008)

- Brian Ulm reported a crash when doing a second SFTP transfer on a re-used

  easy handle if curl_easy_reset() was used between them. I fixed it and Brian

  verified that it cured his problem.

- Brian Ulm reported that if you first tried to download a non-existing SFTP

  file and then fetched an existing one and re-used the handle, libcurl would

  still report the second one as non-existing as well! I fixed it abd Brian

  verified that it cured his problem.

Michal Marek (6 Mar 2008)

  Michael Calmer)

 o crash when doing Negotiate again on a re-used connection
