Can you tell why this is needed?  The current code is how we say this
in a lot of places, and I don't think I see why it's bad for l10n.

I thought there was a typo with the lack of space between the ... and the "done" and the lack upper case after a ... punctuation mark. If it is not, I'm fine with the original.

It's not a typo.  We hove many dozens of these all over the place.

Thanks.
