Updated the BIP draft with an example and a few corrections (like the 
redundant parameter).

You can see the diff here 
https://github.com/greenaddress/bips/commit/636d5819c1be9cc099dca0a47a3148332

Allow me to recap BIP changes in discussion:

- making some changes to allow merchants to offer discounts in case of 
instant ?
- allowing multiple signatures ?

Did I miss anything? Thoughts on the above from others?
