I was one of those people. But above all, I want the following two
properties to hold:

A. Assuming 5-1 is not an error, then the effect of
   LISTGROUP groupname 5-1
MUST be identical to the effect of
   LISTGROUP groupname.

B. Given that the reported High and Low watermarks are known, then the
effect of
   LISTGROUP groupname Low-High
MUST be identical to the effect of
   LISTGROUP groupname
even when the group is empty, which implies that 5-1 means an emtpy range,
rather than an error.

Clive's latest text satisifies both these properties, but sets the
current_ly_ selected group to the first article regardless.

I would still prefer it to be set to the first article of the returned
list (if non-empty), but will defer to the majority view. BUT, if the
returned list is emtpy, then it would still have to select the firsrt
article in the group in order to preserve those two properties.
