diff result may not always have `patch`

At least I get this error:

JsonError "key \"patch\" not present on the JSON: Object (fromList [(\"status\",String \"diverged\"),(\"merge_base_commit\",Object (fromList [(\"sha\",String \"3054cf9a85619efb66a4923367532307477db619\"),(\"committer\",Object (fromList [(\"repos_url\",String \"https://api.github.com/users/pcapriotti/repos\"),(\"following_url\",String \"https://api.github.com/users/pcapriotti/...

Can you give an example repo & commits, so I can create a test for this?

It happens for this URL: https://api.github.com/repos/nomeata/codespeed/compare/ghc...tobami:master

Some of the entries in commits do not have patch.
