The change is quite simple, but a comment in fileops.c says that this behaviour
is retained for sysv compatibility:

...
int
_IO_new_file_underflow (fp)
     _IO_FILE *fp;
{
  _IO_ssize_t count;
#if 0
  /* SysV does not make this test; take it out for compatibility */
  if (fp->_flags & _IO_EOF_SEEN)
    return (EOF);
#endif

...

I'm not sure if this is valid anymore, so I'll try to find out what the current
status is, unless someone here already knows the answer.
