Hm...  I guess it would be possible to update the Summary buffer, too,
but it'd be pretty awkward -- do we want to redo the threading, for
instance?

We could update the headers in the Article buffer easily enough, but on
the other hand -- if the user wants to respond to this in clear text,
hitting `C-d' first is easy enough, and ... do we want to encourage
responding to encrypted stuff in clear text?  (I mean, if we just
rewrite the Article buffer Subject/From/etc headers, then hitting `r'
will use those, and then we might reveal...  stuff...)

What does the Autocrypt header do?
