Nice.  Is it easy to package as a gnulib module?  I think I would want
to use this.

FWIW, I see two advantages, although small both ones: the function
would have the same C fingerprint as printf, so you could use it as a
drop in replacement.  Secondly, you might want the length without
doing strlen; and if x*printf support it, you could have '\0x00'
inside the string, so using strlen wouldn't even be correct.
