zsh:functions:mvln: Bug fix and multiple arguments

Support multiple arguments now with a behaviour similar to `mv`.

Fix that the created symlink did not point to the right file when mvln
was used to rename directories. In that case it pointed to a
subdirectory with the old name. Fixed by moving the directory check of
the target before the `mv` call.
