to change magic tag name

Yes, you can have any class displayed by default with the map display, 
but that is aimed at displaying anything that can be placed on a map, 
not anything as a map itself.

So no, using -D in options.wrm is not the same as changing the magic 
qualities of the magic tag "Map".  The code that calculates and displays 
maps requires the Map tag to be used and I do not believe that we should 
change the acedb code this way.  With hindsight, we could have 
constructed a fully tag2 system, which would have allowed

	Map Linkage_group ?Linkage_group #Map_position

but we didn't, and too much would break for us to make that change in 
the code now.
