In fetch_resolve(), if the port number or service name is included in
the host argument (e.g. "www.freebsd.org:443"), the service pointer, which is supposed to point to the port or service part, instead points to the separator, causing getaddrinfo() to fail. Note that I have not been able to trigger this bug with fetch(1), nor do I believe it is possible, as libfetch always parses the host:port specification itself. I discovered it when I copied fetch_resolve() into an unrelated project. MFC after: 3 days
