JLine is not restoring terminal settings appropriately on some linux environments

[GoogleCodeExporter]

The following behavior was observed on several linux platforms (Ubuntu 
9.10 was one of the ones mentioned):

a) interactive interpreter

        - issued "quit;"

        => terminal messed up (stdin seems to be swallowed and not 
re-echoed)

    b) interactive interpreter

        - issued control-c

        => terminal OK

    c) CMD < test.jaql

        => terminal messed up (same result as (a) )

    d) CMD --batch test.jaql

        => terminal OK

There seem to be small differences in how JLine resets the terminal:

diff jline_stty original_stty
9c9
< isig -icanon iexten -echo echoe echok -echonl -noflsh -xcase -tostop -
echoprt

---
> isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -
echoprt

If there is a bug in jline, lets post a work-around on the wiki:

   e.g., -Djline.terminal=jline.UnsupportedTerminal

Let's also try and properly restore settings in jaql's shell script, 
something like: 

$ export RESTORETTY=`stty -g`

< start/stop jaqlshell>

$ stty `echo $RESTORETTY`

Add "disable" work-around in Revision 540.

On Fedora, all use cases work flawlessly. 

My guess is that whenever you hit CTRL+C, the restore STY commands are not be
executed. So do we need these commmands at all? I believe that we disabled them 
on
Linux some time ago...

Problem turns out to be related to using the IBM jdk.  Jline restores the 
console
correctly with the Sun jdk.
