Help needed with IOChannel example

["Murray Cumming" <murrayc murrayc com>]

I recently updated this example so that it builds. But it doesn't do
anything, and I'm not very familiar with this part of the API:
http://cvs.gnome.org/viewcvs/gtkmm/examples/book/input/main.cc?view=markup

I think it's meant to show the use of Glib::signal_input(), which I think
is a simple way to use IOChannels.

This is the version that was in gtkmm 1.2:
http://cvs.gnome.org/viewcvs/gtkmm-root/examples/input/input.cc?view=markup

This is the relevant bug:
