signals for line numbers in statusbar

[Olivier Sessink <olivier lx student wau nl>]

Hi all,

I want to show the current line number of the "insert" mark from the gtk-2
text widget. Which signals should I use to update the number? The
"move-cursor" seems to be the most appropriate, but it is not emitted when
the user uses the mouse to change the line, or if the user just hits the
enter button. Any ideas?

thanks,
        Olivier
