Hi Alessandro,

sorry for the delay. I have reviewed the patches and they look perfect to me.
Two minor remarks about the documentation -- the CURLOPT_SSL_FALSESTART.3 man
page is not added to and the option is not mentioned in the
curl_easy_setopt.3 man page -- both trivial to fix.

Unless anybody objects, I would be happy to merge those patches!
