I added a patched version of cl-indent.el in to the SLIME CVS version.
I think I fixed a bug that particular caused bad indentation for ","
and ",@" even if lisp-backquote-indentation was t.  The "def.*"
heuristic can be disabled with by setting
lisp-prefix-match-indentation to nil.

Hacking the indentation code is not particularly easy and it would be
nice if to have a test suite for this stuff.  

I would like to submit the changes we make to cl-indent to the Emacs
maintainers and therefore we should be a bit careful with copyrights.
Every Emacs contributor has to sign papers and assign the copyright to
the FSF.  So everyone who sends a patch for cl-indent which is larger
than a page should also willing to do assign copyrights.

Helmut.
