  --- BEGIN ISSUE ---
   _margv  for macros seems to be missing
  At one point in time, arguments to macro's could be obtained from _margv , but this seems to be missing now ( https://github.com/ipython/ipython/wiki/Cookbook:-Macro-arguments ).  
  
  I searched the entire ipython folder and only found _margv in the documentation in the macro.py file. 
  
  Just wondering if this is still supported.
