after-insert

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

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

No internals locks are set when this method is called.
