Commit 13208bf5a7c91a6406195139f1068f173ccdac94 added range support to the `move` command, but applied the wrong offset to the `to` variable. When the source range is before the current song, and the song thus gets decremented by the range size, then the final destination offset must also be decremented by the range size.
