not clear.  
emacs already installs many info files into /usr/pkg/info.

If we do /usr/share/info, we need to rationalize that, and patch all
info readers to look in both places (since there are packages that add
info nodes which aren't already in our tree.)  Which doesn't really
fit very well with the intent of a top-level directory containing all
Info nodes.

I spose just using /usr/pkg/info (or /usr/pkg/share/info) for intree
info files breaks our own hier(7) rules, right?
