I have come up against precisely this problem.  I think that the scrolled
window horizontal scrollbar only updates if the width of the contained
window changes, and long lines don't cause the width of the text widget
to change; the lines just get truncated to the width of the widget.

My solution (which I have not tried yet) is to manually resize the widget
to be wider than the longest line of text (using gdk_text_extents(),
perhaps to get the length of the line).  Perhaps there's a better way?

There will be a less kludgey way to do this when the text widget supports
horizontal scrollbars directly, perhaps.
