According to this screenshot, the problematic button is the first one,
because on my system the first one doesn't have the left and the top
border lines, and neither do all the rest.

I see that xterm does something special in x_draw_relief_rect when the
line width is exactly 1 pixel, and w32term.c doesn't do that.  maybe
that's the problem.
