Thinking about this a bit, it would work to add a third column to the 
types listing, call it "Title", and define it as something like "short 
distinctive phrase using whole words" or something like that, and with a 
note in the manual that the title would ideally be phrased to be 
suitable for a menu of types.  This lets it occupy a middle ground 
between the ultra-short string that is suitable for a subcommand in the 
CLI, and the fully description that is suitable to head up a listing of 
objects.

I'll work up a patch along these lines.  In keeping with the apparent 
tradition of numbered columns in the listing of types :-), I'll supply 
titles as "col2".
