Please make sure that:
1. You _really_ are running from CVS.
2. In your ipythonrc file, you have
multi_line_specials 1
Without this, it won't work.
For me, the above gives:
In [1]: for i in xrange(3):
...: cd
...:
/home/fperez
/home/fperez
/home/fperez
Double check those two things and let me know.
