Update cli_printActionPreamble.sh:
    
        - Do not limit file verification to just regular files. Remember
          that documentation entries have dependent entries and they are
          stored inside a directory. In order to remove the directory that
          stores dependent documentation entries such directory should be
          passed to the list of entries we want to remove and if that list
          doesn't accept directories when passed through
          cli_printActionPreamble then the elimination flow would stop
          without perform the elimination action at all.
    
        - Use default file verifcation (`-a') instead.
