theory.html doesn't appear to address this.

On 2008-03-18, some name changes were made:

	Calcutta -> Kolkata
	Saigon -> Ho_Chi_Minh

Both reflect changes made well before 2008; for example, the respelling of Kolkata occurred in 2001:

The first of those changes is the one closest to Kiev vs. Kyiv - the latter isn't just a respelling, it's a renaming, and apparently also corresponded to the incorporation of some other districts outside what was Saigon into the city.

Presumably, the same way that those other changes were made; a Link line is added to the "backward" file, so the old name remains for backwards compatibility, as a link to the new name (at least if you're using a file system that supports links).

Perhaps Calcutta -> Kolkata, although that one may not have been as politically sensitive as this one.
