Comment 2 for bug 793541

I often do 'V S' or some other virtual folder and use 'A' to archive those messages. I'm wondering if the confirmation prompt might be annoying for people that do that. I can see the merit for a big INBOX with a random collection of read & unread messages, however. I guess I like the prompt, and hitting 'y' after 'A' isn't very burdensome. But I could see someone asking in the future for a way to disable that or set some sort of threshold (message count?).
