test for the mbox utils. (copy_file_chunk): fixed a nasty bug.

2000-01-17  bertrand  <bertrand@helixcode.com>

	* tests/test9.c (main): test for the mbox utils.
	(copy_file_chunk): fixed a nasty bug.
	(camel_mbox_write_xev): create the copy file descriptor
	with the proper arguments. Exceptions implememnted.
	(camel_mbox_write_xev): changed the way bytes are counted.
	No more uses the message size cause it did not take into
	account the message separators characters.
	(camel_mbox_write_xev): hopefully fixed the last bugs.
	works ok now.

Summary information / X-Evolution header generation should all
work ok now.
