Output of curl 7.50

This was originally reported as a curl bug:
https://github.com/curl/curl/issues/983

Curl/libcurl 7.50 fails to establish HTTPS connections on Wine with an
SEC_E_INVALID_TOKEN error.
See the comments on curl bug report for more details: it seems to be because
curl is passing an empty input buffer to InitializeSecurityContext (it works
when passing NULL instead).

It works on Windows.

To reproduce: wine curl-7.50.exe https://google.com
