"""Script to update a failure list file to add/remove failures.
When adding, will attempt to place them in their correct lexicographical
position relative to other test names. This requires that the failure list is
already sorted. This does not guarantee that the tests will appear neatly one
after the other, as there may be comments in between. If the failure list
is not sorted, sorted blocks may be produced, but the list as a whole will not.
Lastly, be wary of lists that have tests stripped from OSS; if you catch that
a test was added inside a stripped block, you may need to move it out.
This is sort of like comm(1), except it recognizes comments and ignores them.
