I'd just suggest adding a reference to the Autoconf git commit that
introduces the new warning:

    See commit 'v2.69-4-g560f16b' of 2012-05-06, "general: deprecate
    'configure.in' as autoconf input" in the Autoconf git repository).

Apart from that, I'm sure Paul has done a good work, as usual :-)

Thanks, and sorry for the noise,
  Stefano
