Subject: [PATCH 1/2] Include common example for fetching PR base-ref
Since this seems to be a common scenario and is generating a lot of discussion (#93), it seems worthwhile to add it to the readme as an example.
I placed it before the other fetch examples because this use-case still only fetches minimal history (only adding one additional ref); so it seems helpful to place this above the other fetch examples which all do deeper fetches.
