Hi Carsten,

I was talking to Jeff Stern about tags todo matching offlist and we
think the documentation for tags-todo matching can probably be improved.

The description of C-c a M at
http://orgmode.org/manual/Matching-tags-and-properties.html
states

C-c a M

Like C-c a m, but only select headlines that are also TODO items and
   force checking subitems (see variable
org-tags-match-list-sublevels). To exclude scheduled/deadline items, see the variable org-agenda-tags-todo-honor-ignore-options. Matching
   specific TODO keywords together with a tags match is also possible,
   see Tag searches.

When I read this I think TODO items is any todo keyword but this isn't
the case.  It is only non-done TODO state keywords.  This makes
tags-todo matching not work for finding tasks to archive (normally
DONE | CANCELLED keywords in my setup)

Should we explicitly state that 'headlines that are also TODO items'
does not match DONE state keywords? Or alternatively should TODO items and DONE items be separate (and explicitly defined) in the documentation
-- like org-todo-keywords and org-done-keywords?

I still think 'TODO keyword' matches any todo keyword defined in
org-todo-keywords and maybe I need to be re-educated :)

Indeed, "TODO" is used in two different ways in the documentation. When I talk about the TODO sparse tree, about the global TODO list (C- c a t), and the tags-TODO match,
this means not-done TODO items.

However, the phrase TODO keyword certainly includes DONE states. I think we should keep it like this, and I will add the not-done in a couple of places where it makes sense.

Here is a patch I am proposing for this.  Please take a look if
this would be sufficient to clarify the issue.
