Linkroll HTML formatting? (ala Delicious's `?fancy`

[Merlin]

Is there a way to have an embedded Pinboard linkroll utilize more HTML
tags? ALA doing something like Delicious's "&fancy" query-string
parameter? <http://delicious.com/help/feeds>

Right now, it looks like the pinboard embed groks b, i, strong, and
emphasis tags pulled from the description textarea, which is swell.

But, I'd love a way, for example, to honor Markdown-style line breaks
(two or more spaces at the end of the line) and list items (asterisks
for OL or "n." for LI). MD-style links would be even sweller, but I
realize that's probably a pain and potentially a risk (Hi, SEO
industry).

Anyhow, if this already exists, pointers to existing ways to do this
would be awesome. I'm using the heck out of this wonderful embed
feature already <http://www.merlinmann.com/roderick>, but humbly
suggest adding further (light HTML-ish) filtering if there's any room
on the roadmap.

Thanks!

Any idea what specifically the 'fancy' operator does, in delicious?
They don't seem to specify it in the docs.

As far as markdown-like behavior, is there any reason this kind of
Markdown-like formatting couldn't be done in JavaScript at display
time? I'd much rather help write that JS code than turn Pinboard
feeds into a templating engine, but there may be some reason I'm not
thinking of.
