"delete-all" macro

[peter horst]

I want to periodically delete all unsaved messages in a given mailbox
(mutt 1.2.5i); to this end I've put the following in my .muttrc:

macro index ".d"  "/eVT.;d$" "delete all messages"

1) Does this look right?
2) Is there a way to include "ask-yes" functionality in a macro? I'd
like to give myself a "Do you really want to delete all" chance...

Thanks very much,

Peter Horst
