Auto merge of #2168 - durka:patch-3, r=alexcrichton

In c9f1b9bf1e535a651f624897bd53a3f81af7501f the format of this example was changed from a `[dependencies.awesome]` section to the newly-recommended inline table syntax, but one of the attributes was left out.

I had to use some slightly weird formatting to keep the comment in place, is that OK?
