Change much of our code to do this, with the help of a byte-compiler change (not comitted) that looked for calls to #'length (which always returns an integer) in its args.

  The table below lists the general-purpose Emacs variables that are
automatically local (when set) in each buffer.  Many Lisp packages
define such variables for their internal use; we don't list them here.
