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.
