DWiki has a new formatting feature. If you write just '* * *' on a line by themselves, they center and become a separator. Like, well, this:
* * *
You can't indent them, because I decided that would run too much risk of confusing things with pre-formatted text blocks.
Why? I just decided I liked that style of chunk separator. (Maybe if I could get a <hr> variant that didn't stretch the entire width...)
Note: feature subject to me changing my mind.
