So the request is to have `C-h v' list all variables that are aliases of
the one we want to have described.  And that does seem useful.

But is that information available?  We have the chain going the other
way in Findirect_variable...  I guess we could loop over obarray and run
that function on all the symbols and create a reverse map?

Is there an easier way?
