The first patch looks fine, the second patch is just enormous.  I am not
against making the code match upstream better as that vastly improves its
maintainability going forward.  So perhaps we could split the second one
out into one "Reorder the code to match upstream order -- no functional
change" which I can then 'ignore' and one which fixes the actual bug.

Obviously even with the larger change we are going to need to test,
test, test but I believe you have this in hand and have a test case.
