Oh, so it ends up making the variable buffer-local before it gets
initialized, so it's both globally unbound and buffer-locally unbound.
Hence when the `defvar` is processed the global value gets initialized
but the buffer-local value stays unbound.

Do you happen to remember why you "needed it many years ago"?

I'm leaning towards considering this a "pilot error".
