I agree that these editorial issues should be fixed.

The point here is that the alpha-2 tags are a very scarce resource, and as
countries change names, the alpha-2 tags change with them.  Eventually
(despite the 50-year delay) tags will have to be reused; since we do
not wish to allow this, we make provision for using M.49 codes instead
of reusing existing codes.
