So, thanks, you seem to have gotten me over one hump... here's my patch:

But now, of course, gnus-warp-to-article doesn't consult the registry to
find out the article's group, so `A T' still fails.  For some reason, it
goes directly to the backend, only one of which supports warping: nnir.

[Aside: it seems like this territory is full of components that could in
principle be nicely generalized, but whose implementation has only been
made to work for one specific usage scenario]

would it work if nnregistry supported warping?  I don't really
understand where/how that backend comes into play.
