 rid of empty directories from the file-list, including nested directories

+Because the file-list is actually being pruned, this option also affects
+what directories get deleted when a delete is active.  However, keep in
+mind that excluded files and directories can prevent existing items from
+being deleted (because an exclude hides source files and protects
+destination files).
+
+You can prevent the pruning of certain empty directories from the file-list
+by using a global "protect" filter.  For instance, this option would ensure
+that the directory "emptydir" was kept in the file-list:

+quote(    --filter 'protect emptydir/')
 
 Here's an example that copies all .pdf files in a hierarchy, only creating
 the necessary destination directories to hold the .pdf files, and ensures
 that any superfluous files and directories in the destination are removed
