Oh sorry, John, I patch really was made on top of current upstream tree, not 
1.3.11. In attachment udpated patch version applied on top of 1.3.11 stable 
tree.

Sorry for that.

And yes, really according to documentation we could match only on set with 
elements of same tyme. On the other hand, an ip type may be easily represented
as prefix with length of max AFI prefix length (32 - IPv4, 128 - IPv6, so I
see no problem using this conversion of ip to prefix type.

Moreover on IPv4 BIRD build there is implicit conversion of ip type to quad
as on IPv4 they basically represent value with same format.

Thanks for your note.
