In the above mentioned bug report, Jonathan Blandford states:

"I originally designed it such that you could draw in the lines, but
that code got dropped along the way.  You'd have to make some changes
to gtktreeview.c to get it working and add a style property so that
themes could turn it on.  I don't think that it's fundamentally a lot
of work though -- most of the information needed at each row is
available.  It's mostly a matter of writing the drawing code."

So if that information is correct, it is not currently possible to
write a theme as described.
