I see. Just curious: what was the reason for this change? I browsed
emacs-devel and bug-gnu-emacs (and etc/NEWS), but I could not find
anything.

Oh, now I see: the pinentry window completely confused me as it was
not particularly verbose concerning the context of its appearence.
It simply asked "Enter passphrase", but it did not say how the
passphrase would be used. -- This is something that has annoyed me
various times, but it is really not (not only) an emacs issue, but
it applies also to gpg.

...Well, it would be nice if either gpg or emacs could tell the user
that the file the user wants to save is just about to go through
symmetric encryption (and not any other encryption mechanism the
user might hope for). Otherwise, any misunderstanding concerning the
encryption mechanism could imply that a file is essentially lost
after saving.
