Also (nits):

1. No need to use #' with lambdas (no advantage in a context that
   expects a function).

2. It is generally a good idea to use a named function (not a
   lambda) on a hook.  For one thing, removing it is easier and
   more robust (`remove-hook') - no worries about differences in
   whitespace etc.

3. Emacs now has `setq-local': `(setq-local VAR VALUE)'.  (I too
   use `(set (make-local-variable VAR) VALUE)', but mainly because
   I usually need code that works also for older Emacs versions.)
