Hmm. I implemented it this way partially after reading your suggestion
in [1], but also to allow using `string_list_split_in_place()` as a
strict replacement for strtok().
And I agree that for the existing users of strtok(), which are all in the
test helpers, this probably doesn't matter much either way. Though I
feel like since we are banning strtok() over the whole tree, that we
should provide a suitable replacement at the time we ban strtok(), not
at the time somebody needs to rely on its non-empty fields behavior.

I think that in general I'd prefer (2) to avoid polluting the list of
declarations in string-list.h, but in this case I think that in this
case it is the right thing to do.
