test/regress/CAE63F5C-b.test and test/regress/CAE63F5C-c.test should both
pass, but test/regress/CAE63F5C-c.test does not, because the total line of
$6.46 is rounded wrong; it should be $6.45.
There seems to be different rounding occurring for totals vs. postings.
This seems to be related to Bug #492.
