Oh, I see. Completion works for me in the "From:" header -- going to the
end of the address and hitting TAB cycles through my addresses -- but I
think that function is provided by my contact management package, not
message-mode. And it doesn't re-run posting styles (ie, nothing else in
the message buffer changes), and it would be nice if it did.
