The callers, and the documentation, all expect int 0/1 to use as the
exit status for the program. Not True/False, even though that works most
of the time.
Some results have errors and no status, others have status and errors.
Update the function to return the final rc to exit with, and a bool
indicating whether or not to continue processing the other fields.
Add a bunch of tests for the new function to make sure I have the logic
correct.
