    gas line buffer handling

    This fixes a segfault when macro definitions end on the last line of a
    file, and that line isn't properly terminated with a newline.  gas
    used to throw away the last line in cases like this, whereas in other
    cases gas added the missing newline.  So I've also made gas
    consistently provide a missing newline.

        * input-scrub.c (input_scrub_next_buffer): Rearrange and simplify
        loop.  Don't drop lines at end of file lacking a newline, add a
        newline instead.  Ensure partial_size is zero whenever
        partial_where is NULL.  Adjust buffer size for extra char.
        (input_scrub_push, input_scrub_begin): Adjust buffer size here too.
