Forgive my ignorance and/or naivety, but unless the client is actually 
trying to list articles in a toplevel group (do toplevel groups even 
contain articles?) wouldn't the group parameter always contain at least 
one hierarchy separator (".")?  If so, "." clearly is not a valid 
character for use in a range, so we *should* be able to differtiate 
between "LISTGROUP <group>" and "LISTGROUP <range>".

Alternatively, we can stipulate that the range parameter can only be 
used if a group is also specified:

LISTGROUP [group [range]]
