port: land the loop decode on the handoff, and note the edit trap

Browse Source 
Second iteration running where a scripted HANDOFF edit failed its
assertion on rewrapped text, leaving the port's page stale while docs/re
had the finding. Patched by reading the file first, and METHOD now says
to check the commit's file count for a silently dropped edit.
