I don't observe any problem with:

emacs -Q -f lisp-mode

in either 22.3 or current CVS trunk.

However, the use of a 2009-06-17 slime-mode snapshot with:

(require 'slime)
(slime-setup)

introduces a one-character shift in the indenting of the last line.

It seems to be due to the use of common-lisp-indent-function. Minimum
recipe:

emacs -Q --eval "(setq lisp-indent-function 'common-lisp-indent-function)" \
   -f lisp-mode


It seems you can set the user option lisp-backquote-indentation to nil
to recover the original indentation.
