exploring levels 5 and 6 of subscribedness

[jidanni@jidanni.org]

There is
S l	gnus-group-set-current-level
but no
        gnus-group-show-current-level
to show the level of the current group. One must dig it out of
.newsrc.eld here in "Gnus v5.11".
Indeed it would be nice to have a command show all the levels of all
the groups. All there is now is "show me all the groups below a given
level".

You see I have this group, "nnml:archive.2008", at level 5. Quite dim
in colour, but I don't want to see it at all there in the *Group*
buffer. OK, I then set it to level 6. But then it becomes
excruciatingly hard to dig it up when I do want to see it. j
(gnus-group-jump-to-group) then refuses to expand its name, etc. The
whole of gnus practically denies its existence. I never had a daughter
named Martha, etc.

At level 5 I could still mark all the articles as read and then it
acts like I want and goes just below the surface of the *Group*
swimming pool, but there are new articles accruing each day so it
becomes unread.

I'm sure http://jidanni.org/comp/.gnus.el isn't to blame.

Wait,
  L runs the command gnus-group-list-all-groups
  List all newsgroups with level ARG or lower.
  Default is `gnus-level-unsubscribed', which lists all subscribed and most
  unsubscribed groups.
OK, I now set the group to level 6, and gnus-level-unsubscribed is 7, but
the group doesn't show up after hitting L. There I am, a victim of a
*Bug* again. There are even unread articles in the group.

By the way, investigating another function,
  (defun gnus-group-list-groups (&optional level unread lowest)
    "List newsgroups with level LEVEL or lower that have unread articles.
  Default is all subscribed groups.
  If argument UNREAD is non-nil, groups with no unread articles are also
  listed.
You forgot to document LOWEST.

P.S. gnus-level-unsubscribed docstring says
  Groups with levels less than or equal to this variable are unsubscribed.
[add "...EXCEPT:"]
  Groups with levels less than `gnus-level-subscribed', which should be
  less than this variable, are subscribed.
But still this is as confusing as the Info page:
     Gnus considers groups from levels 1 to `gnus-level-subscribed'
  (inclusive) (default 5) to be subscribed, `gnus-level-subscribed'
  (exclusive) and `gnus-level-unsubscribed' (inclusive) (default 7) to be
  unsubscribed...
You probably should just make a table.
