This patch could have used a prep patch that had all consumers
of option_origin use remote_name instead, with this adjustment
to the way to use option_origin:

Then this patch introducing the config option would have a
very limited change in the builtin consisting of these two
hunks:

> +	if (!strcmp(k, "clone.defaultremotename") && !option_origin)

...

Interesting that you moved this test. Probably not necessary, and
just a mistake.

I didn't notice it earlier, but perhaps this subshell should be split
into its own multi-line section as follows:

But even better, this is only one line so using
"git -C clone-default-origin rev-parse" is simpler:

This could be done using "git -c clone.defaultRemoteName=from_config" instead
of setting the global config.

And you use the -c option here.

We have the extra newline in these tests, too.
