intermediate notif (1.4.5)

Dear all,

Thanks for your great work.

Setting dlr-mask=31 makes *intermediate notif* bit turns on in 1.4.5.

unfortunately in 1.4.5 documentation, no information exists about it. (I'd
found it in 1.5.0 manual)
I'd tested with dlr-mask=27 and the  *intermediate notif* bit turns off too.

Sincerely,

Hadi
