I think `getline_after_eof`, `getline_feof`, `getline_feof_check` are checking
not much more cases than `error_getline` (and `error_getdelim`) in
_stream_error.c_ and can be removed. Even if not removed, such tests (that
check `feof` and `ferror` and related warnings) should put into
_stream_error.c_.
