[BRLTTY] brltty-6.8

[Sébastien Hinderer]

Hello,

Here is a behaviour I observe and think is a bug. If so one may want to
have it fixed for 6.8.

I use stty cols 80 rows 25 to make it easy to reproduce but this is not
mandatory.

Steps to reproduce

1. Activate autospeak in BRLTTY's preferences menu

2. Open an editor on a file which has more lines than the terminal

3. Scroll down with the cursor.

For the first lines, each time the cursor reaches a given line this line
is spoken by BRLTTY which is, I think, the expected behaviour.

When the last line of the terminal is reached, it gets spoken, too.

But if one arrows down once more, then allthe text will shift so that
line 26 of the file will be displayed on line 25 of the terminal,
assuming no status bar or so.

At this stage the expected behaviour (I think! ) is that this line gets
spoken, too.

The behaviour I observe, though, is that BRLTTY does not read this line
and none of those reached by continuing to scroll down with the down
arrow key.

My hypothesis to explain this behaviour is that BRLTTY decides whether
it should speak or not based on theposition of the cursor or the braille
window. Since that does not change, BRLTTY does not speak but it fails
to notoce that, it's always the same region of the screen which is
rendered in braille its content has been updated and the line should
thus be re-pronounced because it is a new line.

I hope the deescription is clear and accurate.

Seb.
