(define-abbrev global-abbrev-table "foo" "bar" (lambda () (unexpand- abbrev)))

unexpand-abbrev in this context has a different behavior from 22.2 to 23.X. The latter incorrectly leaves point before the expanded (and subsequently unexpanded) text. At some point, unexpand-abbrev was re- implemented in lisp, and its save-excursion seems to cause this. This impacts modes which unexpand abbrevs during the abbrev hook in quoted text or comments, where they shouldn't be expanded.
