If you look at patch39, you'll see 4 different bundles without having a
very clear idea of which one you're supposed to review exactly.  What
would make this a lot easier is if you could see attachments in the
context of the message that talks about them.

I think we need to research how to improve our templates to display this
information.

I think it *must* be very doable because if you click on the permalink
for an individual message, you do get such a view:
http://bugs.darcs.net/msg10420 so Roundup has (thankfully) preserved
these associations.

I'm going to mark this as need-implementation because I don't think we
need any other research steps.  Just study how messages are rendered and
copy the bits and pieces you need?

Fixed thanks to a nice idea from
http://www.roundup-tracker.org/cgi-bin/moin.cgi/MsgFile

I used a stripped down version which preserves all pre-existing behaviour 
except for the bit that adds a list of attachments to each message
