Hi All!

This is some experimental code I came up with.

(message "gnuslog-file %S %ssubscribed to." gnuslog-file
	 (if
	     (gnus-gethash
	      (format "nndoc+%s:%s"
		      (expand-file-name gnuslog-file)
		      (file-name-nondirectory gnuslog-file))
	      gnus-newsrc-hashtb)
	     "is "
	   (if (gnus-group-make-doc-group gnuslog-file 'guess)
	       "has now been "
	     "could not be ")))

I'm not happy about with it, since checking gnus-newsrc-hashtb looks
too implementation-specific to me.

Is there a better way (in gnus-version "Gnus v5.10.7" if possible)?

Also, is there a distinction between subscribed and unsubscribed nndoc
group?

It didn't seem so according to my experiments.

Another thing:
When I debug above form with
M-f11 runs the command edebug-defun
and gnuslog-file is not in gnus-newsrc-hashtb, then some output of
gnus-group-make-doc-group gets inserted into the source buffer
(gnuslog.el in my case)!

Best regards,

Adrian
