update-shape.py and shape-doctor.py: no NEXT line pre-fills --accept-local for a locally edited shape copy, so the apply a row names, pasted, meets update-local-drift and its question to the human instead of re-pinning the edit as the standard, and a shape/ collision copy merged into its original and removed is merged-away to check, whose apply drops its pin row behind the same yes, so an adopted root that did its follow-up validates green again (#501, #502) - #512
