[BRLTTY] brl.cursor and electric fence error report

[Jason White]

My reply from earlier today doesn't appear to have made it to the list, even
though my Postfix log shows that it was accepted by Dave's server. So, at the
risk of duplication, I'll summarize:

I was able to reproduce the problem with the earlier svn revision, where
contracted braille was in effect and the cursor was to the right of the
display window.

With Dave's fix applied as of the latest revision, BRLTTY no longer writes
beyond the end of the buffer, but when the window is advanced to the location
at which the cursor ought to appear, no cursor is presented. That is, the
cursor is absent until the display window moves to a different screen line,
which is evidently another bug induced by the fix.

A grateful note of appreciation is due to Dave and Samuel for their excellent,
highly responsive and effective bug fixing efforts.

As evidence that progress is being made, today I was unable to reproduce the
crashes that formerly occurred following display powerdown, which strongly
suggests that the memory corruption bugs fixed over the last week were
responsible.
