use system_raw in terminal, even on Windows `system_raw` uses `os.system` instead of `utils.process.system`, and makes more sense in a Terminal session. There was discussion that it should be otherwise on Windows, but I can't find any actual evidence for why this would be the case, and there are very clear disadvantages to not using `os.system` (see #978 and #181). closes gh-978

CodeMirror in IPython

We carry a mostly unmodified copy of CodeMirror. The current version we use is (please update this information when updating versions):

CodeMirror 2.15

The only changes we've applied so far are these:

diff --git a/IPython/frontend/html/notebook/static/codemirror/mode/python/python.js b/IPython/frontend/html/notebook/static/codemirror/mode/python/python.js

     var doubleOperators = new RegExp("^((==)|(!=)|(<=)|(>=)|(<>)|(<<)|(>>)|(//)|(\\*\\*))");
     var doubleDelimiters = new RegExp("^((\\+=)|(\\-=)|(\\*=)|(%=)|(/=)|(&=)|(\\|=)|(\\^=))");

In practice it's just a one-line change, adding \? to singleOperators, surrounded by a comment. We'll turn this into a proper patchset if it ever gets more complicated than this, but for now this note should be enough.
