2000-06-30  Jeffrey Stedfast  <fejj@helixcode.com>

	* camel-folder.c (camel_folder_copy_message_to): New function, to
	copy a message from one folder to another. The default
	implementation just uses append_message, but providers can
	implement more efficient versions for use when both folders are on
	the same store.

	* broken-date-parser.[c,h]: Utilities for parsing broken
	date strings.

	* providers/imap/camel-imap-folder.c (imap_move_message_to):
	(imap_copy_message_to): Implemented.

	* camel-mime-utils.c (header_decode_date): Wrote some code to try
	and un-mangle broken date formats and then parse that new string
	instead.
