Comment 6 for bug 981991

More follow-up, all using the test file:

Print "Hi, Richard"
ex

1) I switched from using bash as my shell to using the default (Windows) shell, with py-shell-name set to "ipython". Completion now works if I press ESC-TAB after the end of the second line.

2) Same as #1, but this time with py-shell-name set to "c:/python27/Scripts/ipython.bat"
Now completion fails again, even with the Windows default shell.
