That's the problem with the current approach: we end up making decisions
which can't be justified.  Whether mode hooks should be run or not
depends on the hook and various other things.  What we *do* know, OTOH
is that `vc-find-revision-no-save`s buffer is not associated with
a file, so setting `buffer-file-name` can result in bugs.
