Magically Re-appearing nndoc groups

[Aharon Schkolnik <aharon@healdb.matat.health.gov.il>]

	I have a number of nndoc groups (ding digests). I have marked
all the articles in all of them as read (c in Group buffer). The
number of unread articles goes to 0, but when I exit and re-enter
emacs, the number of unread articles goes back up. For example, I
currently see:


  [ Ding -- 218 ]
         4: nndoc:ding-rn-digest-v95#101
        27: nndoc:ding-rn-digest-v95#102
        28: nndoc:ding-rn-digest-v95#103
         7: nndoc:ding-rn-digest-v95#106
        16: nndoc:ding-rn-digest-v95#80
        14: nndoc:ding-rn-digest-v95#86
        30: nndoc:ding-rn-digest-v95#90
        29: nndoc:ding-rn-digest-v95#91
         9: nndoc:ding-rn-digest-v95#92
        30: nndoc:ding-rn-digest-v95#93
         2: nndoc:ding-rn-digest-v95#94
        11: nndoc:ding-rn-digest-v95#95
         5: nndoc:ding-rn-digest-v95#96
         6: nndoc:ding-rn-digest-v95#97


	BTW - how do I delete these nndoc (digest) groups when I've
finished with them.
