How can I show two dashes on Fluther?

I just answered a question where I quoted a Linux command, and many Linux commands (including that one) include parameters that start with two dashes.

On Fluther two dashes become one em-dash and I don’t see a way to present normal dashes as originally intended. I also really hate “smart quotes” and especially when dealing with command-line or programming answers would like to know if there is a way to display verbatim text for them and other punctuation
