Thanks for this!

Thanks, I was looking for something like that. I see two minor problems though : -line 35 I'm pretty sure it should be [^_] instead of [^*] since you want any characters except underscores. -line 26 I don't think you need a \n in front of the first

, and it actually produces an extra at the beginning of your text when you use paragraph() then textile().
