    Allow SHA1 as reference for inputs

    Support specifying upstream and additional branches to import via
    SHA1s.

    Check for pattern character '*' in provided patterns to determine which
    to treat as patterns and which as explicit revisions.

    Include additional test function to check converting all refs to SHA1s
    as input, and an additional scenario to check passing in a relative ref
    using '~' to pick a different commit to the head of the branch.
