Might have to do with the FIXME in lread.c:

DEFUN ("read", Fread, Sread, 0, 1, 0,
       doc: [...])
  (Lisp_Object stream)
{
  if (NILP (stream))
    stream = Vstandard_input;
  if (EQ (stream, Qt))
    stream = Qread_char;
  if (EQ (stream, Qread_char))
    /* FIXME: ?! When is this used !?  */
    return call1 (intern ("read-minibuffer"),
          build_string ("Lisp expression: "));

  return read_internal_start (stream, Qnil, Qnil);
}
