Not sure why it let-binds these vars, but that's OK, it might indeed be
the best solution to your problem.

I think having it make-variable-buffer-local would not help (tho it
might happen to silence the warning because the check is not done well
enough).
What you want then is to explicitly (make-local-variable <var>) before
let-binding those vars.
