[REQ] Feature Request : gnus-fancy-posting-styles

[François-David Collin]

Hello,
        
        What about extending the gnus-posting-styles syntax to
        something like nnmail-split-fancy, with deep hierachical
        nesting?  For example I'd like to say

(setq gnus-fancy-posting-styles 
      '(& (("X-Home-Page" "http://blah/fradav")
	   ("X-Attribution" "fd"))
	  (| (message-mail-p
	      ((address "frad@thing")
	       (signature-file "~/.signature"))
	      (& ((header "from" "\.fr")
		  ((signature-file "~/.signature-french")))
		 ((header "Organization" "myorg")
		  ((Organization "myorg")
		   (signature-file "~/.very-serious-signature"))))
	      (message-news-p
	       ((address "frad@nowhere"))
	       (& ("^rec.humor"
		   ((signature my-funny-signature-randomizer))
		   ((header "X-Funny" ".*")
		    (("X-Funny" some-extra-X-funny-quoting))))))))
	  ("java"
	   ((signature-file "~/.javanese-signature")))))


Where (largely inspired of the fancy mail splitting doc)

1. If the posting style is a list of posting attributes, they're taken
   as is.

2. (to-match (LIST-OF-ATTRIBUTES) (SUB-POSTING-STYLES)), if the
   to-match expression is matched, the list of attributes are
   applicated and the list of sub-posting-styles are parsed.

3. (| POSTING-STYLES...) If the posting-style is a list, and the first
   element is `|' (vertical bar), then process each POSTING-STYLES
   until one of them matches.  A POSTING-STYLES is said to match if it
   will cause the corresponding list of attributes to be applicated

4. (& POSTING-STYLES...) if the posting-styles is a list and the first
   element is a `&', then process all POSTING-STYLES in the list

and so on...
