New and improved approach to fetching an entire folder summary that should
2000-07-13 Jeffrey Stedfast <fejj@helixcode.com> * providers/imap/camel-imap-folder.c (imap_get_summary): New and improved approach to fetching an entire folder summary that should be much much faster than the old way as it gets the entire folder summary in 1 shot rather than requesting message by message. As with the last update, this version also only fetches the minimum number of header fields. svn path=/trunk/; revision=4141
