As an alternative, it would be nice to have some config syntax for
"clear the list". Maybe something like an empty string, which I think
has no meaning for the current multi-valued variables (at least not for
credential helpers or refspecs). That would allow something like:

  git -c credential.helper= clone ...

to do what you'd expect.

I've been thinking of -= instead. It's unambiguous. And you can use
wildcards on both sides. "credential.helper -= *" means delete that
key, "credential.* -= *" deletes all credential.* keys.
credential.helper -= abc only deletes it if the previous value is abc.
