Add tests checking this behavior.
Currently,
fetchGit
behavior does the following when working on a local git checkout (with branches "master" and "dev"):fetchGit ./.
, HEAD=master, clean: -> masterfetchGit ./.
, HEAD=master, dirty -> master+changes to tracked filesfetchGit ./.
, HEAD=dev, clean -> master (!!)fetchGit ./.
, HEAD=dev, dirty -> dev+changes to tracked filesThis PR changes behavior so that the item marked (!!) above follows the pattern and uses "dev" instead of "master".
This is particularly relevant as of 6d80870: cloning nix, checking out a branch, committing changes, and then using release.nix to test it.... results in building 'master' instead! 馃槙
