Crashes when dragging to IMAP mailboxes, simplifying preferences

[Steve <balsa-user wallfamily us>]

I have had problems in both the 2.0 and 2.2 versions of balsa, where if I drag 
a message to an IMAP mailbox that is not currently open, balsa crashes.  This 
was very consistent and repeatable.  I wrote a patch that checked the mailbox 
and opened it if necessary in mailbox_imap.c, but I can't seem to get the crash 
consistently anymore.  Has anyone else seen this behavior, or is my patch 
totally irrelevant, and I'm having some other problem?

Also, I recall seeing a message some time ago questioning whether "Re" and 
"Fwd" should be translated.  I would have to say that I don't think it should, 
based on the IMAP THREAD=REFERENCES draft, which specifically calls out "re:" 
and "fw:" or "fwd:".  Hardcoding these to Re and Fwd would simplify preferences 
as well.  I also note that the "JWZ" threading does not conform to this draft. 
I've hacked on this as well, but my code strictly follows the draft in that it 
does not handle translations of "Re" and "Fwd", nor does it handle the user-
configured strings or the popular "Aw:".  It's not well tested either.

On the subject of reducing preferences, what do people think of getting rid of 
the "reply prefix" pref?  Seems like the people on the list leave it at the 
default of ">", and I recall seeing a comment that implied an RFC specifying 
this as the "correct" prefix.   A quick search didn't get me any details, 
however.  I would not object to removing the configuration for the "Quoted Text 
Reguler Expression", either, as long as the default value worked well (which it 
has, for me).
