Linus Torvalds 0189de695c Do gasmix as an empty element XML too
Let's make it a goal that the XML we output is pretty.  That clearly was
never a goal for the Suunto XML, but we can be oh-so-much-better than that.

I still don't love XML, but let's try to make the best of a bad situation,
and take pride in what we do.
