        * diff.c diff.h io.c sdiff.c util.c

        Revise to handle Windows lines (\r\n) and Mac lines (\r).
        This entailed modifying all line loops that looked only
        for \n to instead look for \n or \r not followed by \n.
        Extensive revisions to find_and_hash_each_line and line_diff.
