Min's implementation (e80f7aa) works for me for defining local magic. 
Compared to finding and editing ipython_config.py, this is _way easier to figure out. 
It might be nice to reference this in either the '%quickref' or '%magic' documentation 
so that it's easy to discover from an interactive session.
