Not so much.  I've already rewritten most of the site to use the new
syntax, and have the added advantage of different background and borders
for the textblock areas.

Er... rather, yes.  Most of what you wrote it true, but I'm already kindof
past that.

I totally agree on special-case fixes, but I can't image that extra newline
being useful to anybody.  Clue me in if you can think of a reason why.

For a general case, do you have a syntax that disables putting <p> around
things?  Besides (:linebreaks:)?

I've already fought that and found that a leading space can be internally
documented well enough for those.

I'm willing to help, but already beyond it I think :-(  I'd rather focus on
removing those <p> tags if we can ;-)
