This is a terribly-named PR which makes lots of changes.
Rework to new architecture for checking out code, which uses git clone --shared instead of the two different approaches I was using in v0.1 and dev branch (which never got shipped, because I decided to go with this instead).
Separate out diff output from everything else. All other output now happens on stderr and the diff still happens on stdout. (I still need to write a test for this, also, I think this addresses #12).
Standardise integration tests a little. I was using "real world" test cases before, which were good, but also huge and so I blew through my Github LFS quota after 5 CI builds. No more; the integration test files are now small enough to fit in the repo.
