Btw, note the "should" there. Because we do seem to have broken that
_again_.  It worked fine at some point, but lookie here:

commit 61e99ab8e35a88b8c4d0f80d3df9ee16df471be5
Author: Joe Perches <joe@xxxxxxxxxxx>
Date:   Mon Jul 30 14:40:21 2012 -0700

    printk: remove the now unnecessary "C" annotation for KERN_CONT

    Now that all KERN_<LEVEL> uses are prefixed with ASCII SOH, there is no
    need for a KERN_CONT.  Keep it backward compatible by adding #define
    KERN_CONT ""

Joe, you *are* the problem here.

So you are literally the person who broke this.

Goddammit, I don't want to hear another peep from you. You broke this
because you wanted to save a few bytes in those strings, and then
*because* you broke it, you then argue for putting those bytes back in
the form of "\n" characters.

Fuck me sideways. You make this big deal about how this interleaving
is a big problem, and at no point did you actually point to the real
issue, which was your very own breakage where you made it all fragile.

Christ.
