Why does anyone care whether printf or putc/puts is used?  Really it
doesn't matter *at* *all*.
I don't object to the patch but if it would up to me I probably wouldn't
bother applying it it either.
Sometimes I just want to "print" something and I don't want to care
whether it is a constant string or a single-byte constant string, or
something more general.
I see these changes as worse than white-space fixes.
