[orca-list] Presentation of contracted braille by Orca

[Jason White <jason jasonjgw net>]

To reproduce:

1. Run Firefox (or another application, for that matter) with Orca and a
braille display.

2. Issue the appropriate command on the braille display to turn on contracted
braille. This, naturally, requires liblouis to be installed and available to
Orca.

Expected behaviour: The contents of the braille window would be split
appropriately on spaces, at the end of a word.

Actual behaviour: contracted words are split across braille lines, i.e., the
display is filled all the way to the last cell, and shifting the braille
window to reveal the rest of the screen line positions the next character at
the start of the braille window, even if in the middle of a word.

BRLTTY at the console level can handle all of this appropriately, and can also
route to appropriate characters when in contracted mode and a routing key is
pressed.

I've also noticed that when in contracted mode under Orca, bullets turn into
horrible hexadecimal numbers!

I would volunteer to help with this if I had time available, which currently I
don't, regrettably. If anyone here knows someone familiar with braille display
technology and Python who would be willing to help, now is the time - I'm sure
Joanie et al., and Orca users would all appreciate it.
