bug#5588: 23.1.50; C-M-d inside string in Lisp mode gets me out of string into unrelated sexp

[Tobias C. Rittweiler]

In a .el, or .lisp file with content

  (frob "foo")

  (bar
    ;; Like "Invoking
    ;; external command".
    (quux))

Move point inside the string "foo", and press C-M-d.

Emacs will move point to (|quux.
