vendor options encoded incorrectly in request

[Colin McInnes]

in my dhclient.conf I setup
option space cisco code width 1 length width 1 hash size 128;
option cisco.controllers code 61 = { array of ip-address };

I'm running dhclient 4.4.3

in my REQUEST, dhclient appears to be encoding cisco.controllers in the
main list of options (ie as DHCP option 61, not option 43 suboption 61).

The server (also running isc dhcp 4.4.3) is correctly encapsulating the
list of IPs as option 43 suboption 61.

What could be causing this?
