without ranges it does get a bit difficult (or rather long) to read if 
there are many vlans (it was also a comment I received on v2).

All the available options whether they apply to the immediate 
sub-command or not are at the toplevel command today.
Hence the position (Not a big fan of the current name. suggestions welcome).

I would have loved to have the default output print ranges, If that is 
acceptable. But, that can break new iproute2 on older kernels (If that 
is something we should care about).

other option is keyword argument like maybe 'bridge vlan show 
compressed' or 'bridge vlan show ranges'

Thanks,
Roopa
