Hi

I am using the following gnus-groupline-format

,----
|   (defvar gnus-user-format-function-g-prev "" "")
|   (defun empty-common-prefix (left right)
|     "Given `left' '(\"foo\" \"bar\" \"fie\") and `right' '(\"foo\"
|       \"bar\" \"fum\"), return '(\"   \" \"   \" \"fum\")."
|     (if (and (cdr right)                  ; always keep the last part of right
|              (equal (car left) (car right)))
|         (cons (make-string (length (car left)) ? )
|               (empty-common-prefix (cdr left) (cdr right)))
|       right))
|   (defun gnus-user-format-function-g (arg)
|     "The full group name, but if it starts with a previously seen
|       prefix, empty that prefix."
|     (if (equal gnus-user-format-function-g-prev gnus-tmp-group) ; line-format is updated on exiting the summary, making prev equal this
|         gnus-tmp-group
|       (let* ((prev (split-string-and-unquote gnus-user-format-function-g-prev "\\."))
|              (this (split-string-and-unquote gnus-tmp-group "\\.")))
|         (setq gnus-user-format-function-g-prev gnus-tmp-group)
|         (combine-and-quote-strings
|          (empty-common-prefix prev this)
|          "."))))
|   (setq gnus-group-line-format "%M%S%p%P%5y:%B%(%ug%)\n")
`----

taken from [1]. Now I would need to see of some groups (all the ones
which have the substring [Maildir] in the name) to see the number of
emails instead of the number of unread emails. How can I achieve this?

Thanks,

Rainer
