Don't default to US-specific locale settings

[maresb]

Describe your changes

I'd expect that if a user wants a particular locale settings they should set it explicitly for themselves. It feels US-centric to default to en_US. So let's still generate the en_US to make it easier in case people want to change it back, but default to the more standard Computer format.

The C option is more sane with things like 24-hr times when running the date command.

Well...

if a user wants a particular locale settings they should set it explicitly for themselves

exactly. exactamente. 確切地.

Makes sense to me. If tests pass, I will merge this.

Haha, thanks @benz0li!

I wonder if there are any advantages to POSIX?

[maresb]

Ah, they are identical. :)
