When I was creating #2792, I wanted a way to write:

"title":http://...

and have it show up exactly as that, except inline, not wrapped in a pre block. '!' will disable text such as [[...|...]] from becoming links, but it doesn't work for links like "title":.... It probably should.

Alternately, there should be a way to turn off wiki formatting altogether for an inline chunk of text (not necessarily a whole block). Pre seems to disable some formatting, but not all: [[...|...]] still becomes a link inside a pre block, for example.
