I rather think I did.  ;-)  But remembering them now, and looking them up
in the manual, dir-local variables are only applied to file buffers when
they are in the pertinent directory.  A `with-temp-buffer' buffer
shouldn't be in any directory, hence shouldn't get any dir-locals.

That's the theory, anyway.

And even if a temp-buffer did somehow belong to a directory, what harm
will it do if it gets the `fundamental-mode' variables?  Probably not
much.
