movemail 3.1, hanging again

Hello Sergey,

I have immediately unpacked and tried the mailtuils 3.1, by thinking
movemail would get all the improvements from last days, but it is
hanging again.

I have tried using the patch, but it has got rejected, now I have
again non-functional version of movemail.

rejected:

   if (stream->ctl == NULL)
     return ENOSYS;

And -u is anyway not working, I guess it searched for UIDL in Maildir,
and if it does not find, it stops operation. It shall be comparing
UIDLS of messages I assume.
