[bug-inetutils] ping: Discard single octets as host name.

[Mats Erik Andersson]

Hello again,

there is an old bug report [1] filed with Debian, which makes much sense.
It is a wish that the call

    ping 10

should return an error, since no host can consist of a single octet,
and neither is an IPv4 address with initial octet 0 possible.

The following patch addresses this natural behaviour, which the default
`ping' of Debian GNU/Linux also complies with. I have by intention left
an outer conditional in place, which while not strictly necessary,
improves the readability of the code intentions.


Best regards,
Mats
