This works pretty good, besides "dev" will be completed after "dev".

I found that we can use "-'false'" as the the guard here:
subcmd_dev=(/$'[[:alnum:][:punct:][:cntrl:][:digit:]]##\0'/ -'false'
':interfaces:network interface:_net_interfaces')
then only network device will be completed after dev:
% ip link show dev<tab>
network interface
em1 lo tun0 wlp3s0
or even using "[]" as the pattern has the same effect:
subcmd_dev=(/$'[]'/ ':interfaces:network interface:_net_interfaces')
But both of them will report parsing error when trying to complete after
the interface:
% ip link show dev lo<tab>
parse failed before current word
