Added redund hints to more tags

Browse Source 
Well, kinda. At the moment we don't have any reund support (it's a
TODO), so arguably redund=0 and this is just a comment tweak.

Though our mdirs _are_ already redund=1... so maybe these should
actually set redund=1?

It's unclear, so for now I've just tweaked the comment, and we should
probably revisit when _actually_ implementing meta/data redundancy.

Note this only really affects struct tags:

This redund hint may be useful for debugging and the theoretical
CKMETAREDUND feature.
