[Dovecot] [patch] example configuration for expire seems broken

The expire configuration in the example config file in 1.1.11 is broken:

root@omega:/etc/dovecot# /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecot Unknown dict module: db expire plugin: dict_init() failed Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf failed!

It's inconsistent with the documentation at http://wiki.dovecot.org/Plugins/Expire, so I've made the attached patch to try and fix it.

Note: I don't know if this new configuration is correct either, because its a new box and I've not got any mails old enough to cause the plugin to try and write anything, but at least I can start dovecot like this. :)
