Description of problem:
I'm unable to use curl with all https:// URLs when my proxy uses kerberos authentization:
curl --proxy http://myproxy:3128 --proxy-negotiate --proxy-user : https://email.seznam.cz
407 Proxy Auth required
when
curl --proxy http://myproxy:3128 --proxy-negotiate --proxy-user : http://email.seznam.cz
works ok.

This bug was already fixed by curl developer(s) in git. Let's see:
https://sourceforge.net/tracker/?func=detail&aid=3046066&group_id=976&atid=100976

I need fix for all supported Fedora and RHEL distributions as soon as possible.
May I add same bug report for RHEL or is this bug report enough for it?

Version-Release number of selected component (if applicable):
$ curl -V
curl 7.19.7 (i386-redhat-linux-gnu) libcurl/7.19.6 NSS/3.12.6.2 zlib/1.2.3 libidn/1.9 libssh2/1.2.4
Protocols: tftp ftp telnet dict ldap ldaps http file https ftps scp sftp
Features: GSS-Negotiate IDN IPv6 Largefile SSL libz

How reproducible:
We have a squid with kerberos authentization.
curl --proxy http://myproxy:3128 --proxy-negotiate --proxy-user : https://email.seznam.cz
407 Proxy Auth required
when
curl --proxy http://myproxy:3128 --proxy-negotiate --proxy-user : http://email.seznam.cz
works ok.


Steps to Reproduce:
1. Install and setup squid with kerberos negotiation auth.
2. curl --proxy http://myproxy:3128 --proxy-negotiate --proxy-user : https://email.seznam.cz
