Ruby on Rails

There are quite a lot of line break issues with Rails on StackOverflow and the web in general. A lot of solutions are ugly and a lot modify simple_format so I've created a patch that I'd like to hear thoughts on before submitting a PR.

I've made a slight modification to split_paragraphs and how it gsubs the newline characters in paragraphs up so that if you pass it a line option, instead of getting rid of all newlines and return carriage characters, it can substitute \r\n for an html break element.

This way if a saved chunk of text is the following then it won't be stripped down to just the 2 lines of text but will have the <br /> tags that were obviously intended:

"\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nBig gap.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nPlease."

This doesn't affect the regular behaviour of simple_format and will still return the usual result without the option.

I find that this isn't an edge case but is frequent enough to warrant this and not have people overriding simple_format and split_paragraphs in their application helper.

Thoughts?
