Correct about the missing quotes and other 
careless slips. Thanks for the polish. 

To put this in context, the results of 

. separate mpg, by(foreign) shortlabel

              storage  display     value
variable name   type   format      label      variable label
------------------------------------------------------------------------
-------
mpg0            byte   %8.0g                  foreign == Domestic
mpg1            byte   %8.0g                  foreign == Foreign

are too long-winded for my graphical tastes. 

For a graph, I'd personally want to zap further "foreign == " 
and the corresponding lines should be more like. 

local eq = index(`"`label'"', "=") 
local label = substr(`"`label'"',`eq'+3,.)  

That's what more or less -labnoeq- does, any way.
