In the two use cases I had here, one wanted to have the final symbol
(for *Help*) and the other wanted to have all the symbols (to check
symbol properties).

An the semantics would be kinda odd -- in the non-alias case, we'd still
return nil, right?  So the user still has to use symbol-function on
something, so I think the current definition (stop at the last symbol)
is the one that's more practical.
