Quick lisp question as I dig into nnimap.el (in my attempt to understand
and maybe improve the fancy split stramash):

Why, in the defun of nnimap-split-incoming-mail, is this written as it is:

(let (
	  (nnimap-incoming-split-list            nil)
          ...
	  new-articles
	  )
...)


And not like this:

(let (
	  nnimap-incoming-split-list
          ...
	  new-articles
	  )
...)


In other words, why is the setting to nil of nimap-incoming-split-list
and news-articles done differently? Just a coding quirk, or a deep and
mysterious reason?

thanks,
Tommy
