[IPython-dev] IPythonInputSplitter.cell_magic_parts and InteractiveShell

I'm working on getting the 0.13beta1 to work with Sage.  One problem is 
that the InteractiveShell code assumes that the input splitter has a 
.cell_magic_parts attribute (see line 2559 of 
IPython/core/interactiveshell.py).  Now, this is not an attribute of 
InputSplitter, but is an attribute of IPythonInputSplitter.  Do we have 
to depend on having this attribute, or should InteractiveShell first 
check for the existence of this attribute?  In Sage, we have our own 
SageInputSplitter which inherits directly from InputSplitter, and so we 
don't have the .cell_magic_parts attribute.

In other words, how decoupled do you want InteractiveShell and the 
IPythonInputSplitter subclass of InputSplitter?
