after-delete (augmentable only) in pasteboard%

Called after a snip is deleted from the editor (and after the display is refreshed; use on-delete and begin-edit-sequence to avoid extra refreshes when after-delete modifies the editor).

See also can-delete? and on-edit-sequence.

No internals locks are set when this method is called.
