Make sure the third word/token (whatever) is "EXPUNGE" and not something

2000-07-28  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/camel-imap-folder.c (imap_expunge): Make sure
	the third word/token (whatever) is "EXPUNGE" and not something
	else like "EXISTS" or "RECENT". When removing the message from
	the summary also make sure to free that data to avoid leakage.
	Also make sure to subtract 1 from the 'id' since IMAP starts
	at 1 and our summary starts at 0 :-)
