One drawback of this approach is that such lines will need to be merged into the appropriate long-term zonenow entry after the date listed.
That shouldn't be a problem in this particular case. After the date listed, the comment line and associated data line should simply vanish. There should then be no need to alter the comment line or comments column for the America/Nuuk ("most of Greenland") line, since Ittoqqortoormiit is in "most of Greenland".
The main reason there's a comment with a date now, is to remind us to remove the comment and the associated data line then. (This is belt and suspenders as "make check" should also remind us.)
You're right that it is an issue in the general case when data lines are removed (or added) in zonenow.tab. That's why zonenow.tab is a separate file. Although I originally wanted to calculate zonenow.tab automatically, there was too much human judgment in its "comments" column.
Thanks for catching the typo. I have more typo fixes on the way....
