Comment:

 The issue isn't in `tor_addr_parse()`, which is backed by a correctly
 implemented `inet_pton()` implementation.  `tor_addr_lookup()` first tries
 to `inet_pton()` the address as `AF_INET` and `AF_INET6`, and falls back
 to `getaddrinfo()` on systems that support it.

 NetBSD (and I assume OpenBSD) both have a `getaddrinfo()` based entirely
 around `inet_pton()`, with code that would make this work `#if 0`-ed out.

 http://cvsweb.netbsd.org/bsdweb.cgi/src/lib/libc/net/getaddrinfo.c?rev=1.112
 &content-type=text/x-cvsweb-markup&only_with_tag=MAIN

 So IMO it's a Net/OpenBSD libc bug, assuming you think they should provide
 a standards compliant `getaddrinfo()` (IEEE Std 1003.1, 2013 Edition
 mandates the X/Open behavior).
