  | If %s were documented as printing the number that would be obtained by

  | without ABI and possibly API changes, can't).

That I agree with, our documentation is lacking.   It should say that.
And more.

  | Where is it documented what works and what doesn't?

UTSL ?   The doc in POSIX (most of which is not being changed) is
better than our man page in this regard.
