I guess it wouldn't be *too* big a deal to download the body of all
messages...I don't get that much mail, thanks to the combination of Gnus
and Gmane...

In that case, would I be able to do what I want by installing a function
as the second element of my split rule in nnimap-split-rule?  Would this
function be called in a buffer containing the entire message body?

Another option would be to do this semi-interactively, which may be what
I want anyway.  Is it easier to call a hook on a message when it is
*read*, rather than when it is split?

Where would I look to learn how to do these things?  Is there a guide to
hacking somewhere?  Or should I just dive into the Gnus code?

Indeed.  

Thanks for your help, Lars!
