This extension to js/bisect-no-checkout adds support for bisecting bare repositories.
It does this by relaxing the requirement that git bisect is invoked in a repository with a working tree and by defaulting to --no-checkout in the case of a bare repository.
Two tests are included to demonstrate this behaviour.

This option may be useful when the test you would perform in each step
does not require a checked out tree.
