That call goes to
git_config_get_value_multi()
-> git_configset_get_value_multi()
-> configset_find_element()
the returned value from there would be either NULL or the list of
values that belong to the config cache layer, i.e. a caller of the
API can peek but is not allowed to modify it.
So if you are modifying the value you obtain from the API, you must
make a copy; otherwise you will "stomp over" memory that belongs to
the config cache layer, not to you.
