I thought of that too, but it picked up a few comments too

...
src/libvirt-domain.c:11105: * "block.<num>.backingIndex" - unsigned int
giving the <backingStore> index,
...
src/util/virnetdev.c:870: * @ifindex: Pointer to int where the index
will be written into


So rather than "wait" I figured get this out there now and see what
feedback I can get to make a rule...

Thanks for the quick review - I'll push what I have and generate
something for the other 'index' uses.
