shell escapes in .muttrc

[Jon Nathan <jon@xxxxxxxxxxx>]

Hi,

I use this in my .muttrc to keep my sent-mail sorted nicely by
month:

set record="~/mail/sent/sent-`date +%m%Y`"

However, it appears that the shell escape is only executed upon
mutt startup.  If I start mutt on, say, Dec 25 and keep it running
over the end-of-month boundary, mail sent on Jan 1 will be stored in
the sent-122003 folder instead of sent-012004.   Of course if I exit
and restart mutt, mail will be saved to the correct monthly folder.

Is there any way around this?
