I realized now that macroexpansion really should not be done without
pretty-printing, the resulting forms are unreadable when they are more than
just a setf -> setq expansion.

So please forget about the above patches, here is one that extends the code in
pp.el by `pp-macroexpand-expression' and `pp-macroexpand-last-sexp'.
The code is now a lot shorter, more readable and the results more usable.

Diff attached, have fun!
