I like that because it makes `find-func' work (cf bug 157123).

Maybe put both .el and .elc in the specific directories like
/usr/share/emacs21/site-lisp when it should apply only to certain
flavours.  (Ie. not in /usr/share/emacs/site-lisp.)

Some tricky postinst could figure out the newness of each flavour to
decide whether there's wanted or unwanted shadowing, but initially
just manually assign to the right flavour(s).
