The `pp-fill` code sometimes end up generating things like:
(foo .
bar)
instead of
(foo
. bar)
so make sure we cut before rather than after the dot (and open
parens while we're at it).
* lisp/emacs-lisp/pp.el (pp-fill): Cut before parens and dots.
* test/lisp/emacs-lisp/pp-tests.el (pp-tests--dimensions): New function.
(pp-tests--cut-before): New test.
