I don't object to this patch, but just as a general comment, in
enterprise-y environments using an old OS (e.g. CentOS 5/6) & then
compiling some selected packages like git based on OS libraries is
quite common.

E.g. at work we're running git 2.12.0 compiled against CentOS 6
libraries, which has curl 7.20.1, released on
Apr 14 2010. Not so long ago we were still running CentOS 5 which
comes with 7.15.5 released in Aug 7 2006 which would break with your
patch.

Whether we support that is another question, I think it's reasonable
to say that if you're compiling git on such an old system you also
need to compile a libcurl instead of using the OS version. I just
wanted to point out that this *does* happen, someone is going to be
compiling new git releases on CentOS 5 & will be hit by this.
