[capi-sig] PyRun_InteractiveOne from string?

[Dave Brotherstone]

Thanks so much.. that looks like exactly what I want to do.  Looks like
you've done a fantastic job on the integration there - makes my weedy little
console look very plain :)

Just need to work out why boost::python won't exec code.InteractiveConsole()
now :)

Thanks again.
Dave.
