    No, you are. Read my answer from two days ago in this thread.

    KERN_CONT is *not* the same as "". Not now, not ever. If you make it
    the same, you're broken.

    The reason is simple: KERN_CONT "<3>" should print out the string
    "<3>". If you make KERN_CONT be "", it will do the wrong thing, and
    think that the <3> is a priority marker.

    Please people, this is subtle, and current code does things RIGHT. Any
    code that changes it to do something else is almost certainly buggy.
    The new semantics had better be the same as the old one.

    The change to verify that 'current' matches the previous printout is
    so far the *only* sane semantic change I've seen in this thread.
    Everything else has been pure garbage.
