Debugging abbrev-file

[Andreas Roehler]

;; Debugging abbrev-files turned out to be hairy
;;  sometimes.  As `define-abbrevs' stops while
;;  encountering an error, this function permits to
;;  jump just at the last messaged cursor position.

;; Probably there are more efficient ways to debug such
;; a file.  Please send your comments, alternatives
;; etc.
