gnus-summary-thread-gathering-function and digests

[Raymond Scholz <rscholz@tzi.de>]

I prefer gnus-summary-thread-gathering-function to use
'gnus-gather-threads-by-references. But for digests this is usually
not a good solution as all the digests I've seen so far don't contain
reference information. 

So for some groups (I receive as a digest) I want to have threading by
subject.

I use:

(add-hook 'gnus-summary-mode-hook 
	  (lambda ()
	    (cond
	     ((string-match "list\.linux\.kernel" gnus-newsgroup-name)

	      (setq gnus-summary-thread-gathering-function 
		    'gnus-gather-threads-by-subject)

	      (setq gnus-summary-thread-gathering-function 
		    'gnus-gather-threads-by-references))))) 


This is probably a little awkward and it even does not work, if you
know a better solution please let me know.

My first thought was to set the threading function in the group
parameters. But digests behave strange (maybe I should say smart), as
they generate a new nndoc group for every digest. This new group
doesn't inherit it's fathers group parameter. 

So is there a good way to set threading on a per group basis even for
digests?

Cheers,
  Ray
