My version had:

"skip can be NULL; extras cannot."

The first thing that function does is:
string_list_find_insert_index(extras, dirname, 0)

And that crashes when extras is null.  So I think my version is correct
here.

Other than that, I've reviewed both the patches themselves and the
overall diff and everything looks good to me.
