Re: KASSERTMSG fix
What would be useful is a format effector that processes a format
string and a va_list (recursive call inside vsnprintf).
But adding non-standard effectors is not really a good idea.
I once added such a thing (I think I used %@). It was easy, but I
never used it very much and never rolled it forward (it was 1.4T I
added it to). Never even got around to adding it to -Wformat.
Note that that doesn't work with our current gcc on machines where
(__builtin_,)va_list is implemented as an array with one element.
That means (AFAIK) all machines where some parameters are passed
in registers, like e.g. amd64 or powerpc. See my PR#45138.
