Implemented (--include, -I)

note that the filters (--exclude and --include) are applied to
top-level devices only. For example:
$ lsblk --include 8
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 149.1G 0 disk
├─sda1 8:1 0 1000M 0 disk /boot/efi
├─sda2 8:2 0 2G 0 disk /boot
├─sda3 8:3 0 9.7G 0 disk [SWAP]
├─sda4 8:4 0 34.2G 0 disk /
├─sda5 8:5 0 63.2G 0 disk /home
└─sda6 8:6 0 39.1G 0 disk
└─luks-10d813de-fa82-4f67-a86c-23d5d0e7c30e (dm-0)

I have a little changed --all option, it's not mutually exclusive to
--include and --exclude anymore. The idea is to print all devices
including empty devices (empty devices are ignored by default), for
example:
$ lsblk --all --include 7
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
loop0 7:0 0 0 loop
loop1 7:1 0 0 loop
loop2 7:2 0 0 loop
loop3 7:3 0 0 loop
loop4 7:4 0 0 loop
loop5 7:5 0 0 loop
loop6 7:6 0 0 loop
loop7 7:7 0 0 loop
