Summary	0001979: conflicting specification for open("existing-directory", O_RDONLY \| O_CREAT, 0644)
Description	The description of open() explains O_CREAT with a paragraph that starts: O_CREAT If the file exists, this flag has no effect except as noted under O_EXCL below. <...> 'file' is of course the XBD 'file' which includes directories, devices, etc. So, open(O_RDONLY\|O_CREAT) naming a directory that exists should behave the same as open(O_RDONLY) of that same path. Then later the ERRORS section contradicts that: [EISDIR] The named file is a directory and oflag includes O_WRONLY or O_RDWR, or includes O_CREAT without O_DIRECTORY, or <...>
Desired Action	Adjust the description of O_CREAT to remove the contradiction.
