In that case all I get is an empty row set in reduce views, and the
total number of rows in the view, not the selection, while doing map
views. However what you say is exactly what I'd like to have: when I
write limit=0 I want couchdb to do a count for me, otherwise limit=0
would be meaningless (instead with all the other limits or no limit
the normal couchdb behavior is good)
