It's probably more useful to say
"This makes GTK+ ignore the return value of your signal handler, and use
the return value of the default signal handler."

You can do it more obviously with connect_notify():
http://www.gtkmm.org/gtkmm2/docs/reference/html/classGlib_1_1SignalProxy1.html#a2

This stuff is rarely needed. Most of the time gtkmm does what you
expect. I don't know whether this is a bug.
