If someone fixes that, please also fix the description of the EINVAL
return from pipe2().
As written, it suggests that the flags can only be (exactly)
O_NONBLOCK or O_CLOEXEC (not both together) - and completely
ignores O_NOSIGPIPE which one would hope does not cause EINVAL.
Rather than repeating the legal flags just say ...
[EINVAL] flags contains an invalid value.
(the text earlier already says what is valid.)
