Argh.

I'm not sure how to get the select method though.  I thought it would
be gnus-current-select-method, but that's always the nnml method, even
when nnimap splitting is done!  I think there's something with the
binding of that variable, and my Lisp is hardly good enough to figure
out those closures or whatever is going on.

So instead I brute-forced gnus-request-scan to set the new variable
gnus-internal-registry-spool-current-method to gnus-command-method
before a request-scan operation, and then gnus-registry.el uses that
variable.  It works very nicely, and I'm happy with the registry now,
but please take a look and let me know if I'm missing something
obvious as usual.

I named the variable gnus-internal-registry-spool-current-method, I
hope that's OK with everyone.  It's certainly long enough that you
can't miss it :)
