   In lisp-mode the indentation of the following expression is wrong:

   (foo
   :bar :a12
   :sie sume )

   If I press TAB at the beginning of the last line I get:

   (foo
   :bar :a12
         :sie sume )

   I think this is wrong, the indentation should be as the first example.
   This was not the behaviour in emacs 21, neither is the beaviour of
   indent-region consistent with TAB.

does the following patch give good results?
here is a description of the change:

        * emacs-lisp/lisp-mode.el (calculate-lisp-indent): Use the
        last sexp that begins a line, instead of the truly last sexp.

can someone suggest a better implementation?
