[PATCH] inet_parse: Clarify IPv6 comment and error message

[Doug Evans]

Wrapping an IP address in square brackets does not necessarily
mean the address is an IPv6 address. The wrapping is just an aid
to parsing since IPv6 addresses have colons, but does not provide
semantic information.
E.g., [127.0.0.1] is a valid way to write 127.0.0.1.
