lisp-mode-hook is called after shell-mode-hook.

Commands:
Delete converts tabs to spaces as it moves back.
Tab indents for Lisp; with argument, shifts rest
of expression rigidly with the current line.
Meta-Control-Q does Tab on each line starting within following expression.
Paragraphs are separated only by blank lines. Semicolons start comments.
Return at end of buffer sends line as input.
Return not at end copies rest of line to end and sends it.
C-d at end of buffer sends end-of-file as input.
C-d not at end or with arg deletes or kills characters.
C-u and C-w are kill commands, imitating normal Unix input editing.
C-c interrupts the shell or its current subjob if any.
C-z stops, likewise. C-\\ sends quit signal, likewise.
C-x C-k deletes last batch of output from shell.
