Personally I prefer %s and the functions.
I think the format specifiers have become unwieldy. I don't remember any
of the kernel specific ones by heart, I always look them up or just
cargo-cult. I think the fourcc format specifiers are a nice cleanup, but
I don't remember them either. I'd like something like %foo{yesno} where,
if you remember the %foo part, you could actually also remember the
rest.
But really if you get *any* version accepted, I'm not going to argue
against it, and you can disregard this as meaningless bikeshedding.
BR,
Jani.
