    [average-balance] tidy loop conditionals
    
    Previously the splits handling used nested conditionals. Rearrange and
    tidy; i.e. handle empty-splits or empty-interval-splits first, and use
    last conditional to test for internal-transactions handling. This
    avoids nested conditionals.
