Function abandon_move

src/copy.c:1486–1501

When effecting a move (e.g., for mv(1)), and given the name DST_NAME aka DST_DIRFD+DST_RELNAME of the destination and a corresponding stat buffer, DST_SB, return true if the logical 'move' operation should _not_ proceed. Otherwise, return false. Depending on options specified in X, this code may issue an interactive prompt asking whether it's ok to overwrite DST_NAME. */
