  $ cp     $HOME/.jnewsrc   $HOME/.jnewsrc.bak
  $ grep : $HOME/.jnewsrc > $HOME/groups-sub
  $ grep ! $HOME/.jnewsrc > $HOME/groups-unsub
  $ cat    $HOME/groups-sub $HOME/groups-unsub > $HOME/.jnewsrc

but i prefer to delete the unsubscribed
newsgroups directly within vim:

  vim -c 'g:!:d' -c 'wq' $HOME/.jnewsrc

it's a simple :global command.  *shrug*

and assuming that all subscribed groups
are already at the top of the file and
that there is at least one unsubscribed
newsgroup following (a line with an '!´)
you can easily sort the subscribed
groups with this command:

 :1,/!/-!sort

 "from the first line unto a line which
  contains an exclamation mark (go back one line)
  pipe them all through 'sort'."  and, of course,
  the input is replaced by output of the command.

easy. :-)
