[orca-list] Interesting issue panning braille display in Gnome-Terminal

[Jason White <jason jasonjgw net>]

Summary: pressing the right panning button on a braille display to 
advance the window fails in GNOME-terminal if the length of the text 
line exceeds that of the braille display (i.e., it won't pan right to 
show the remainder of the line, but it will move to the next line if the 
current line is short enough).

Steps to reproduce:

1. With a 40-cell braille display, under GNOME-Terminal, start a Python 
interpreter.

2. Run the following:

print("-"*40)

3. Move the braille display to the output line, and press the right 
panning button. The display moves to the following line correctly (i.e., 
the Python prompt).

4. Repeat the above with a string length longer than the width of the 
braille display (e.g., 60). Pressing the right panning button has no effect.

I have Orca configured not to split words between braille lines, and 
with contracted braille enabled. This also occurs if there are spaces on 
the line (i.e., a line of regular text - such as a manual page).

Debugging output can be supplied, as requested.
