Moving back to Inside each source followed an existing linked folder in the
destination and could replace a file outside the source (Codex P1). A target
nested inside the thumbnail folder in use was accepted, and the old-copy
cleanup then removed the previews just copied there (Codex P2).
Every copy now checks the whole destination chain for links, also when the
folders exist, and the move refuses a folder inside the one in use with
location-inside-current. The cancelled branches no longer mix explicit and
implicit returns (code-quality note).
