Summary: SOCK_* flags in getaddrinfo hints->ai_socktype
Description:
getaddrinfo description says

"The ai_socktype field to which argument hints points specifies
the socket type for the service, as defined in socket."

the "socket type as defined in socket" is unclear now:

it may mean the type argument of socket() (which since 0000411 includes
SOCK_CLOEXEC and SOCK_NONBLOCK flags) or only the socket types without
flags (as defined in XSH 2.10.6).

in other words one might interpret the text so that

hints.ai_socktype = SOCK_STREAM|SOCK_CLOEXEC;
getaddrinfo(host, port, &hints, &p)
...
sock(p->ai_family, p->ai_socktype, p->ai_protocol);

is idiomatic getaddrinfo usage, instead of

hints.ai_socktype = SOCK_STREAM;
getaddrinfo(host, port, &hints, &p)
...
sock(p->ai_family, p->ai_socktype|SOCK_CLOEXEC, p->ai_protocol);

Desired Action:
Clarify ai_socktype with respect ot the new socket type flags.
