Description
LineBox on the curses screen in PyPy looks funny:
The easiest way I've found to reproduce this with core Urwid is to hack the terminal.py example to use the curses screen:
diff --git a/examples/terminal.py b/examples/terminal.py
index 18edba1..f709131 100755
--- a/examples/terminal.py
+++ b/examples/terminal.py

Research direction
Start with examples/terminal.py and its use of urwid.curses_display.Screen, then reproduce the LineBox rendering problem under PyPy using the shown change. Trace the curses screen path involved in drawing LineBox and compare its output with the expected rendering. Done means the LineBox displays correctly on the curses screen under PyPy.
