If you look back at the wiki example, you'll notice it uses 
<episodeshort> rather than <episode>.  For whatever reason, get_iplayer 
has always populated the "episode" field in the programme metadata, even 
if it's just a fallback value of the programme name.  The "episodeshort" 
field is typically a stripped version of the original "episode" value 
with episode numbers removed, etc.  In the extreme case where there is 
no original "episode" value, "episodeshort" is empty.  Check your 
programme with --info and you'll see that "episode" is populated, while 
"episodeshort" has an empty value placeholder "-".

The new file prefix format is really only useful with <senum> and 
<episodeshort> since all the other metadata fields will almost always be 
populated.  It was implemented primarily to make it easier to create 
output file names compatible with XBMC scrapers. I've added a note to 
that effect in the wiki page.
