Area change

@Jheald, Melderick, Arbnos:

Now that we have this new property, I added it to a few counties/Alaska census areas.

• Q494216#P793 (see w:Bedford_County,_Virginia#History). Looks like Wikipedia (and Wikidata) still needs to add seven square miles to the area value (and an addiitonal area (P2046)-statement).
• Petersburg Census Area (Q503028) see Q503028#P793. I added creation and dissolution there to be able to use the qualifier.

Seems that we might have a lot of changes that aren't tracked/included. --- Jura 15:26, 14 February 2020 (UTC)

Adding a area (P2046) qualifier to clarify the amount of area that was transferred might be nice, too. Jheald (talk) 15:30, 14 February 2020 (UTC)
