I restarted emacs and added the above.  I was editing some C code, pressed
enter and got:

	Debugger entered--entering a function:
	* my-watcher(auto-fill-function nil set nil)
	  newline(nil 1)
	  funcall-interactively(newline nil 1)
	  command-execute(newline)

auto-fill-mode didn't seem to turn on, though - I'm not sure if that's to be
expected.  It's also not the first time I pressed enter in that buffer.
