Generally I think program should define system abbrevs to
differentiate from abbrevs defined by the user. And each time
define-abbrev-* runs, the abbrev definitions are overwritten anyway.

The attached patch does this. BTW, defining system abbrevs doesn't
change abbrev-changed so I leave the (let ...) out.
