bug#31271: 25.2; exported deleted RMAIL emails should have theit deleted flag reset

[Francesco Potortì]

In Rmail, suppose you want to archive your last received email to two
different mboxes.  Then you 'o' to the first one, then 'o' to the second
one.  After the first one, the email is marked as filed, deleted.

I argue that the 'deleted' flag should be reset when archiving the email
to the second mbox.
