   @private handle_item
-

   Render an item either by looking it up in the the temporary cache,
   or by using the appropriate mime handler. Once the item is rendered, it 
   is stored in the temporary cache under a key which combines the item_id,
   any extra HTML parameters, and a flag which specifies whether the item
   was merged with its template. <br>
   This proc takes the same arguments as the individual mime handlers.
- 
+
   @param item_id  The id of the item to be rendered
- 
+
   @option revision_id {default The live revision}  
     The revision which is to be used when rendering the item
- 
+
   @option no_merge    
     Indicates that the item should NOT be merged with its
     template. This option is used to avoid infinite recursion.
- 
+
   @option refresh     
     Re-render the item even if it exists in the cache.
     Use with caution - circular dependencies may cause infinite recursion
     if this option is specified
- 
+
   @option embed    
      Signifies that the content should be statically embedded directly in
      the HTML. If this option is not specified, the item may
      be dynamically referenced, f.ex. using the <tt>&lt;include&gt;</tt>
      tag
- 
+
   @option html
      Extra HTML parameters to be passed to the item handler, in format
      {name value name value ...}
- 
+
   @return The rendered HTML for the item, or an empty string on failure
