GitHub-Flavored Markdown Comments

Comment forms allow some HTML, this plugin extends that to let users type in Markdown and have it automatically converted to HTML. It also extends Markdown with a couple features made popular by GitHub. Conversion from Markdown to HTML is completely automated and doesn’t require anything on the commenter’s part.

The feature additions from GitHub are:

• Single linebreaks are treated as new paragraphs
• Code “fencing” with three backticks (“`)

Two notable features from GitHub’s Markdown implementation are missing:

• To do lists: Doing these well would require some front end interaction, which I decided is outside the scope of this plugin at least for now
• Repository autolinking (e.g. comments, issues, etc): These seemed a little too GitHub-specific.
