[orca-list] Small bug when using BRLTTY in a graphical terminal

[Sébastien Hinderer <Sebastien Hinderer ens-lyon org>]

Hello,

I am using BRLTTY rather than Orca to work in graphical (mate)
terminals. BRLTTY can be configured to show which part of a screen it
currently displays in braille by selecting that text. When this setting
is enabled and BRLTTY is used to follow a graphical terminal while Orca
is running, then Orca will say "text selected" and "text unselected"
each time the braille window is moved.

I also believe there is a glitch with the french translation: "not
selected" and "unselected" seem to have both been translated by "non
sélectionné", which is wrong. "unselected" should be translated by
"dé-sélectionné" (the dash matters for the text to be pronounced
correctly).

Best wishes,

Sébastien.
