A good argument for the format by @xaviershay  is that you get less [incidental change]( http://www.rubytapas.com/episodes/24-Incidental-Change ), which makes your [git history easier to use](http://mislav.uniqpath.com/2014/02/hidden-documentation/). If this doesn't change a lot, it doesn't matter much. Personally I tended to use the style @myronmarston suggested, but am switching to what @xaviershay uses because I noticed I do get a lot of unrelated change.

(as a sidenote, I didn't think of using `\` on the first line, that's a neat trick)
