My thinking was just to initialize `expand-list/pos/index` in skeleton.el, so
that a skeleton-command could populate `expand-pos` with locations from
`skeleton-positions` even before expand.el has loaded.

I think `skeleton-positions` was intended as a building block for users
(or package authors) to create jumping capability of their own.  For
example, an emacswiki article[1] proposes one way of doing this.  I'd
want to avoid renaming `skeleton-positions` or changing the value it
receives, since that would probably break such configurations.
