I would like to turn plain URLs appearing in markdown source code into a <a> elements, like most Markdown implementations do. I particularily like doing this for footnotes, where a plain clickable link is usually expected rather than obscuring the link target with a custom name. Currently I have to repeat myself by giving the same name and target to the link. This is very slightly annoying since there’s hardly any reason to not auto-link plaintext URLs.
In case I didn’t miss an obvious way to do this, is this a feature you’d be interested in implementing, as an opt-in or opt-out [markdown] config option?
