I did expect it to be overriden while in the shared field, because it
should take pages from the preferred store, with these stores in this
order:
1. wikifarm/wiki.d
2. pukka-core/wikilib.d
3. wikifarm/wiki.d
4. wikifarm/wikilib.d

What I didn't expect was for the skin's version to be overriden while
I was in a different field.  I thought the preference order was:

1. testing/wiki.d
2. pukka-core/wikilib.d
3. wikifarm/wiki.d
4. wikifarm/wikilib.d

But testing showed it was 

1. testing/wiki.d
2. wikifarm/wiki.d
3. pukka-core/wikilib.d
4. wikifarm/wikilib.d

I think I agree that it is a feature, not a bug.  One more weird step
to add to the installation instructions, though.

I thought so -- it explained how I could set $WikiTagline and have it
just work when the template wanted it.
