[VM] Question about behavior of vm-save-message

[rpgoldman]

I was trying to experiment with some earlier advice (for which many thanks) 
that I should get Thunderbird-like behavior (hidden deleted messages) by using 
a virtual folder with the "undeleted" selector.

This seemed to work nicely, but then I had an oddity when I tried to save a 
message with "s" -- vm-save-message.  When I did this in the original IMAP 
INBOX folder, I was prompted to save the message to an IMAP folder.  This 
seemed to me to be the correct behavior.

However, when I was in the virtual folder, I got a very different behavior.  I 
get prompted "Save in folder: ~/" which seems to me not to be The Right Thing.

Is this something I am doing wrong, or is it something that necessarily follows 
from the generalized nature of VM virtual folders?

Many thanks,
