note 113522 deleted from function.unlink by cmb

Note Submitter: james at dunmore dot me dot uk ---- I know it is obvious, but.... if you have nested symlinks (for example, we archive into yyyy-mm for backups, and symbolic link to make our directory structure look flat - don't ask), unlink will only delete the top level symlink (as expected). If you want to delete the actual file, you'll need to use readlink. If you want to delete all of the files and the symlinks, you'll need to recurse up and down to achieve that.
