Hi,

I encountered an error which occurs creating a group that had already
been seen ephemerally.  Here is a procedure to reproduce the trouble
that I saw.

(1) Call `gnus-group-enter-server-mode' and enter *Server* buffer.
(2) Select a server, and open an unseen group ephemerally.
(3) Jump to *Group* buffer.
(4) Call `gnus-group-make-group' and specifies the group, the backend,
    and the server which you saw in the 2nd step.  You will recieve
    the following error message.

        Group backend+server:group already exists

In order to avoid this problem, I propose the attached patch.
But, I have noticed that this issue had already been discussed 5 years
ago and 2 years ago.

	* gnus-srvr.el (gnus-browse-read-group): Don't pass fully
	qualified group names to `gnus-group-read-ephemeral-group'.

    2003-04-13  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* gnus-srvr.el (gnus-browse-read-group): Don't give the real name
	to the ephemeral entry, but the prefixed name.

Therefore, I worry that my proposal has ill effects.  Which change is
right?
