Upcoming small incompatible change

[Moon at MIT-AI (David A. Moon)]

In the next system, SORT-SHORT-LIST and SORTCAR-SHORT-LIST will be removed\n from the global package.  The new functions STABLE-SORT and STABLE-SORTCAR,
which are probably what you wanted if you were calling the others, will appear.
This was done mainly to make the documentation not look like a kludge.
