[PATCH] Simplify and correct header trimming before feeding to bogofilter

[Michael Shields <shields@msrl.com>]

I sent this patch a few days ago, but mail.gnus.org ate it.

	* spam.el (spam-bogofilter-articles): Use message-remove-header
	to remove headers; the old way incorrectly removed just the first
	line of folded headers.
