[dev] Git imp not expunging moved messages

[Chuck Hagenbuch]

I have git-imp basically running now. However, messages moved to  
another mailbox (either through drag-n-drop, or when deleting a  
message + using a trash folder) aren't being expunged.

I traced this down into Imap_Client trying to get back up to speed on  
this code, before giving up. Here's a debug trace of what happens when  
I delete a message. It does get copied to my trash folder, just not  
expunged from my inbox.

Actually, now that I look at the log more closely, this looks like a  
potential problem:

C (1231984739.2115): 6 UID STORE 1:* -FLAGS.SILENT (\deleted)

Because of the 1:*, isn't that resetting the deleted flag on the  
message (UID 383844 in this case) that ought to be getting expunged?
