`eval-buffer` will evaluate (defvar ...) in the normal way, which does
*nothing* if the variable is already defined.

So I suspect that "re-eval the whole ..." above meant to use C-M-x which
has special support for `defvar` to force re-evaluation.

Of course, that's what it's for.  This "purpose" should be thought
of as a type.
