* Fill in deps if not provided with heads Before this change, if heads were passed without deps they would be silently ignored, which could be confusing. See #8334. * Use "dep" instead of a blank string This is the customary placeholder dep. It might be better to show an error here instead though. * Throw error on heads without deps * Add a test * Fix tests * Formatting * Fix all tests * Fix a test I missed * Revise error message * Clean up whitespace Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com>
