/** The gncScrubBusinessLot() function makes sure that the indicated
 *    lot has all the correct properties required for a lot used in
 *    the business features.
 *
 *    Currently this function only does one thing: eliminate lot link
 *    transactions between invoice lots and payment lots (which were
 *    generated by GnuCash versions 2.6.0-2.6.3). Lot links
 *    between invoices and credit notes will still remain.
 *
 *    Scrubbing the lot may cause subsplits to be merged together,
 *    i.e. for splits to be deleted.  This routine returns true if
 *    any splits were modified or deleted.

 *
 *    * check if the split is
 *    part of a transaction that was generated as the result of a doubly
 *    posted invoice/bill/credit note. Refer to
 *    https://bugs.gnucash.org/show_bug.cgi?id=754209 to learn how this
 *    could have happened in the past.
 *    If such a transaction is found, its read-only status is removed and
 *    a warning is written to the trace file. Considering the user may
 *    already have added a correcting transaction we leave it up to the user
 *    to decide whether to also delete the transaction or not.
 *
 *    * remove empty splits, on condition they aren't part of an invoice transaction.
 *    In this case the function returns true so the caller knows a split was removed.
