[PATCH v2 1/2] dir.c: make last_exclude_matching_from_list() run til the end

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

The next patch adds some post processing to the result value before it's
returned to the caller. Make all branches reach the end of the function,
so we can do it all in one place.
