Subject: [PATCH] Integration: transform.move on content reports the ids it
 moved (#521)

#521 makes transform.move return {moved, ids}; next's move_content (the content-selection path, content?) returned only {moved}. It returns the ids of the items whose content or frame moved, and copies_report_their_ids checks it.
