Markdown and `<address>` tags

[Shaun Inman]

Turns out Markdown wraps `<address>` tags in `<p>` tags which is invalid
according to the W3's validator. I thought I had a simple fix for this
problem by adding `address` to the RegExp on line 374 of Markdown.pl but
there was no change in the behavior. Am I missing something?

I'd also like to report that Markdown _is_ being parsed in my RSS feeds (I
don't mess with TrackBacks though).

Cheers.
