We can't simply blank the "comments" column, because the user interface for 
tzselect currently looks like the interaction quoted at the end of this email, 
and if the last four lines say simply "1) 2) 3) 4)" the user won't know what to 
select. Presumably there would be similar problems with fancier user interfaces 
employing this data.

The "(most areas)" comment in Ukraine is similar to comments used in Australia, 
Canada, and other countries. Perhaps you can suggest better comments identifying 
the three smaller regions involved. Comments should be in the English language 
and aimed at an English-language audience.
