Re: [tz] [PATCH 2/5] tzselect.ksh: regions list to inclusive

The regions list criteria was only based on country. This caused, for example, all of Australia to be listed under the regions for Antarctica > Australia.

Here, I think the current behavior is intended. The idea is that if one selects (say) the United States, it's common to want to select Hawaii next, even if one came to the United States selection via North America rather than via the Pacific. That is, the selection is not via a tree but is via a DAG, and the difference matters when a country crosses continental borders. The same comment applies to the later patches that assume this one.
