        During a transaction, the actual changeset data is already stored in the
        main file, but not yet finalized in the on-disk index. Instead, a
        "pending" index is written by the transaction logic. If this function
        is running, we are likely in a subprocess invoked in a hook. The
        subprocess is informed that it is within a transaction and needs to
        access its content.

        This function will read all the index data out of the pending file and
        extend the main index."""
