If you're proposing that we change the behavior of inet_aton(), I don't
think that's much of a solution, since then people who do remember the
old notation ... or recognize the analogy to IPv6 abbreviations, which
are not a lot different ... would get burnt.  We can't do it anyway on
most modern platforms, unless we want to replace all of getaddrinfo()
which seems pretty unappealing.
