This seems to imply that callers of create-file-buffer will now have
to remember to ensure the argument ends in a slash if it is the name
of a directory.  If so, I'd prefer that create-file-buffer did that
internally, when its argument is a directory.  Callers shouldn't know
to much about the internals of the callee.

Does this changeset have any user-facing behavior changes?  If so,
they should be at least in NEWS.
