[Bug libc/282] New: POSIX.1-2001:popen streams are byte-oriented

["a dot josey at opengroup dot org" <sourceware-bugzilla at sources dot redhat dot com>]

POSIX.1-2001 states that pipe streams created by popen() are byte-oriented
(1003.1 2004 edition p 874 l 28526)
Yet running a program such as the following extract shows they are not after
a call to popen.

 if ((fp = popen(cmd, "r")) == NULL)
        {
            /* popen failed */ ;
        }
                                                               
  
  if ((ret = fwide(fp, 0)) >= 0)
       {
         printf ("fail\n");
        /* fwide is expected to return < 0 to denote that
            the stream is byte oriented but is returning 0
            to denote no orientation */      
       }
