See rmail-write-region-annotate: it switches to the right buffer just
in time for write-region to save the correct text, but buffer-size is
called before that.

IMO, using annotations for the job of saving the mailbox is also a
horrible kludge.  All that just to avoid defining an Rmail-specific
binding for C-x C-s ...
