bug#15907: 24.3; Emacs crash due to substitute-command-keys and after-change-functions |

Emacs crashes whenever `substitute-command-keys' is invoked and one of
the functions in `after-change-functions' contains a call similar to
`(format "%s" 1)'.
To reproduce:
1. Start `emacs -Q';
2. Evaluate the following two statements:
(add-hook 'after-change-functions (lambda (&rest a) (format "%s" 1)))
(substitute-command-keys "\\{emacs-lisp-mode-map}")
3. That's it. Emacs crashes.
The crash doesn't happen if you replace the number 1 with a string or
a symbol, but it does also happen if you replace it with a list.
This is most annoying as it causes a crash whenever `describe-mode' is
invoked.
