Agreed.  Plans are for a nice tabular output and this is now also on my 
local TODO list.

Implementation will be delayed somewhat, at least until there is more 
than one command to display.  The testsuite provides some test data 
here, but the "test" commands have much shorter names than the 
"production" commands that are planned.
