Details:

When octave or octave-cli is started as a background job, and then brought to
the foreground again, the terminal settings have not been initialized
correctly, when compared with running in the foreground.


$ ./run-octave -q &
[1] 11616
$ fg
./run-octave -q
>> system stty;       ## typed, but there is no echo
speed 38400 baud; line = 0;
lnext = <undef>; min = 1; time = 0;
-brkint -icrnl -imaxbel iutf8
-icanon -echo
>> quit
$ stty
speed 38400 baud; line = 0;
-brkint -imaxbel iutf8


This behavior has existed since Octave 3.8.2. Octave 3.6.4 was able to start
and initialize in the background correctly.

Starting Octave in the foreground and then backgrounding works fine.
