Just out of curiosity, I ran this in a fresh repository and got a
segfault. An attached patch obviously fixes it, but I am wondering
if a better "fix" is to teach for_each_string_list_item() that it is
perfectly reasonable to see a NULL passed to it as the list, which
is a mere special case that the caller has a string list with 0
items on it.
Thoughts?
Thanks.
