50ae31e6f6 Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the same problem as addressed by [2af630c572].

0c4de2d96d A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code.

not previously occurred in over 8 years of heavy use, that is not seen as
a serious problem.
