For instance, as I've been working on adding Markdown features I was 
surprised to discover that DDoc's current support for backtick-delimited 
code only works within a single line. Most implementations I've seen 
allow it to span hard-wrapped lines, as long as it's within a single 
paragraph.

I'd like to support as many Markdown features as we can, but there will 
always be a some differences--particularly those that conflict with 
existing DDoc features.
