Cleaned up a bit, now uses imap_next_word() (camel_imap_command_extended):

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

	* providers/imap/camel-imap-store.c (camel_imap_status): Cleaned
	up a bit, now uses imap_next_word()
	(camel_imap_command_extended): Now uses imap_next_word(). When
	checking for RECENT, allow the first digit of the recent-count
	be between 0 and 9 inclusive instead of exclusive.

	* providers/imap/camel-imap-folder.c (imap_expunge): Optimized.
	No longer will it need to reload the summary as it now instead
	removes the appropriate message summaries from the cache.
	(camel_imap_folder_changed): If recent == 0 then return. If
	recent < 0 then just emit the folder_changed signal, don't reload
	summaries.
