Ctl-Z doesn't throw EOF error in raw_input()

[ironpythonbot]

Ctl-Z throws an EOFError in raw_input under CPython but simply returns the empty string under IronPython. Error occurs with both 2.0.1 and 2.6 A1

CPython:
Python 2.5.4 (r254:67916, Dec 23 2008, 15:10:54) [MSC v.1310 32 bit (Intel)] on win32

This breaks the code module, which expects EOFError to terminate its interact loop.

The issue is in PythonFile::ReadLine

// Read characters up to and including a '\r\n', converted to '\n' (or until EOF or the given size, in // which case the string will not be newline terminated). public override String ReadLine(int size) { StringBuilder sb = null; // start off w/ some text if (_bufPos >= _bufLen) ReadBuffer(); if (_bufLen == 0) return String.Empty;

That last item should probably be:

if(_bufLen == 0) throw PythonOps.EofError(string.Empty);
