Hello!

I would like to display not just the number of unread articles for
subtopics in the topic line, but also have the number of groups include
the subtopics.


For 'gnus-topic-line-format' variable add 'G' element to allow for
display of number of groups in subtopics

	* lisp/gnus/gnus-topic.el (gnus-topic-line-format)
	(gnus-topic-line-format-alist, gnus-topic-prepare-topic)
	(gnus-topic-insert-topic-line, )
	(gnus-topic-display-missing-topic, )
	(gnus-topic-update-topic-line):
	Provide number of groups in subtopics for topic line display and
	add 'G' element to be used for 'gnus-topic-line-format' variable

	* doc/misc/gnus.texi (Topic Variables):
	Document 'G' element for 'gnus-topic-line-format' variable
