Hey Adam,

Perfect, I'm hoping I can submit this as a PR so one could add ?revs=true on:

/_changes
/_design/*/_view/*
/_find

It's actually incredibly easy to add to the first two just a few tweaks to how 
the HTTP params are parsed and used, Mango is a bit trickier since it proxies 
to the mrview API's but I'll see what I can do.

Hopefully I can submit this as a PR after I'm finished.

Cheers,
Robert
