I recently completed a feature in tork that utilises the bandwidth history. I 
dug a bit more into how i would  use the 'extra-info' option to retrieve the 
bandwidth history in future and have a couple of notes/questions:

There's currently no way of getting extra-info for just one descriptor from 
the control interface. Tor either downloads extra-info for all descriptors or 
none at all. What would be the best way of making extra-info available on 
demand from the control interface?

Should tor download extra-info for a router if it receives a getinfo 
server/desc/fd/xxx for that router, in anticipation of a possible extra-info 

Or would a setevents extra-info interface be better? If enabled, this would 
provide an asychronous extra-info message body for every server/desc/fd 
request received.

Also, there are a couple of typos in control.c, one of which prevents getinfo 
extra-info/digest from working.
