We also provide no way in "git config" to properly interpret a
value. E.g. does a "user.email" showing up twice for me mean I have two
E-Mails at the same time, or does the last one win?

Actually --get knows this. Single-valued options can be handled
correctly quite easily. It's --get-all (or rather, the future
--get-multi because we can't change --get-all's behavior) which can't
interpret values because there's no standardized way of doing it.

Right. We need a hint from the caller about how they expect us to
interpret the values. And I agree we should probably introduce a new
verb instead of modifying --get-all, which some callers might be
expecting to do their own list processing.

Likewise in the C code. We probably want to leave existing callers of
git_config_get_value_multi() alone, and give them a new
git_config_get_string_list() or something.
