This is more in line with what I'd personally come up with than the
existing syntax, but it's very different from what the hundreds of
current MediaWiki users expect. I personally dislike "\\" for line
breaks, as I'd expect a literal \ or \\ instead, but that's a
relatively minor point overall.
I'm naturally opposed to any non-ASCII markup, for obvious reasons,
but from an idealistic perspective this isn't a bad start.
