Here is a patch to add - as an alternate skeleton character.  - operates
exactly as _ in setting skeleton-point, but does not interact with the
region wrapping effects.  This means that @ is completely unaffected and
remains as just the method of setting the skeleton-positions.

This allows Stefan to have a character to use for marking skeleton-point
without wrapping the skeleton around the point.  It also allows mmm-mode
to continue to use both @ and _ in their skeletons without suffering
under the undesired semantics of the modified meaning of @ introduced by
Stefan's patch.  I hope that this solves the issue for everyone.
