I think that the latter would be the best soln. When I look up a widget (e.g.
GtkToggleButton), it would be *MOST* useful for the devhelp page to list all possible
signals that are applicable for that widget.

I imagine that this might be a lot of work though, and I don't know if the devhelp pages
support #include (to lessen the reduncancy)... But I think it would be Really Useful...
