FETCH on save

[Kyle Wheeler <kyle-mutt-dev@xxxxxxxxxxxxxx>]

I’ve noticed that whenever I go to save a message from one folder into 
another (via IMAP), mutt issues a

   a0016 UID FETCH 785 BODY[]

Why does it do that?

I have a hook like so:

   save-hook "~h 'X-Spam-Status: Yes'" =Spam

If I comment-out that hook, mutt doesn’t do the FETCH and saving a 
message is much faster (especially for large messages). I would think 
that would be the end of it, except I have

   set imap_headers="X-Spam-Status"

in my ~/.muttrc. Is that not enough? Is there a way to get it to stop 
sending a FETCH every time? Is there a better way to get the same effect 
from my hook (maybe using mutt’s scoring features)? If not specifically 
for purposes like this, what is imap_headers used for?
