One possible issue I have is that I was hoping that eventually we
can discard "git http-fetch" altogether sometime in the future.
Does anybody still use the dumb HTTP transport seriously?
And the first move in that direction would be to allow the system be
built without http-fetch, even if git-remote-curl (and its aliases)
would still be built to access smart-http transports.
So, I am not sure. This is just the matter of adding an out-of-line
hidden option used only for environment inspection, so if it can be
done to git-remote-curl, that would probably be much more future
proof.

OK. We probably can also take the compile-time "NO_CURL" into account,
so that we can tell a misconfigured installation that wanted to have
CURL but failed to install a usable http-fetch and an installation
that deliberately omitted anything cURL?
