I just tested with truncate-lines. Same bug as with word-wrap.

Both `word-wrap' and `truncate-lines' are defined using
DEFVAR_PER_BUFFER. My guess is that there is a bug in DEFVAR_PER_BUFFER
or something related to that.

Stefan, could it be that you forgot about `permanent-local' when you
implemented this?

In a new buffer evaluate this:

  (put 'word-wrap 'permanent-local t)
  (setq word-wrap t)
  (kill-all-local-variables)

and then look at word-wrap. It is nil, but it should be t.
