John's fix for bug #713 changes the way basis cost are calculated.
The patch also fixes#712, which caused ledger to create automatic
Equity:Capital Gains that were not correct. Update the test cases
accordingly after verifying the new output.
This option reports only in terms of the annotated price of the
commodities involved, otherwise it reports the amounts themselves. It
can be used in conjunction with other reports, as it applies to the
displayed amounts, not the actual amounts being calculated.
