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

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

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.
