Small bug with IMAP + terminal resize

[Vincent Lefevre <vincent@xxxxxxxxxx>]

I have the following bug when using IMAP:

1. I start Mutt, which displays "Password for x@xxx:".
2. I enlarge the terminal (e.g. gnome-terminal or xterm).
3. I enter the password. Mutt displays the mailbox index, but
   at this point, it hasn't noticed the terminal resize yet.
4. I type a key, e.g. Page Down.

The key isn't taken into account by Mutt, but at this moment,
Mutt notices the resize and redisplays the index.
