Where exactly (commit id) are you applying the patch?

GtkScrolledWindow is introduced by the patch series - I'm confused:
Which patch series did you try and where?

I can make truncation the default behaviour (in fact it is),
the problem is the presence of the scrolledwindow which is necessary
for the fix introduces extra padding. I'm not sure there's a way to fix 
that (well, I guess there is but it's a little tricky as it means the
scrolledwindow has to appear and disappear entirely from the widget 
hierarchy).

I might be able to fix it with a style change, if I can defeat the gtk3 docs
and figure out if/how to set a style property on a widget.

That's pretty old... even on oldstable I have 3.14. I can try and find a 
system with that version of GTK, wondering if it's a GTK bug.
