Indexed content does take away some storage space, I would guess roughly about 
10% of the size of the indexed files, but that's just an approximation and it 
also depends on the type of database that you are using.  The documentation 
was supposed to indicate that it uses much less space than full insertion.  
If you can point me to the ambiguous passage, I'll certainly try to improve 
that.

I don't see that it would make too much sense to have 2 quota options.  
Especially since gnunet-insert does *remove* "worthless" migrated content in 
favour of indexed content.  You should only hit the quota if your indexing 
surpasses the quota disregarding the migrated content (assuming that the 
priority given for locally indexed content is sufficiently high, the default 
of 50 should be fine).

Aside of that I consequently don't understand the need for such an option, it 
would be quite difficult to implement this type of segregation of DB quotas 
efficiently (without ending up with 2 DB lookups per query instead of one).
