        * disasm.c: Update copyright to include 2004.
        (do_mixed_source_and_assembly): For uiout asm list
        and tuple cleanups, initialize to null_cleanup instead of
        NULL and do so prior to loop.  Only reset when we close off
        the tuple/list.  Move check for whether to close off the
        asm tuple/list to after dump_insns call where it will be run
        on each loop iteration.
