Description

1. the tab completion completely messes up the screen. if I run
bin/client.bat or bin/karaf.bat, everything looks perfect.

2. TAB without anything before it used to give the complete list of
commands, now just adds a space on the line.

3. CTRL-D just beeps. I have to run "logout" to close the Putty session
cleanly.

4. Running non-editor type commands, like bundle:info should not put me in a "vi like" mode. CTRL-C just beeps, can't just hit return to go back to
console. Have to use 'q'.

5. Running 'help <any command>' produces a blank screen, then once you 'q' out, some (like 'watch') show: gogo: NullPointerException: "in" is null!

The previous shell was much more intuitive and easy to use - IMHO.

NOTE: if you try #5 in bin/client.bat, you get the gogo:
NullPointerException and in the karaf.log:
