The readmore plugin won't do this currently.
Any ideas on how you might want to implement this? Maybe a configuration
variable for flavours readmore should operate on which defaults to all of them?
The readmore plugin is very useful to keep a short frontpage, with a link to the
full article, i.e. using the html flavour.
However, when users fetch the rss/atom feed, I always want to give them the full
version of the article. It seems this is not possible?
