I found `gnus-newsrc-hashtb' has all the group names that
`gnus-newsrc-alist' holds.  So, I'm not quite sure since I have
not tested it thoroughly yet though, the problem I brought up
--- j doesn't work for groups having not activated --- can be
fixed with:

--- gnus-group.el~      2019-04-01 21:28:54.404887500 +0000
+++ gnus-group.el       2019-04-08 04:19:19.117882300 +0000

                       group)))

This looks to fix Lars' bug#35070 as well.  I'll check and check
it with investigating other issues...
