CLI usability: autocompletion clears input on pressing TAB twice
----------------------------------------------------------------

                 Key: AS7-2059
                 URL: https://issues.jboss.org/browse/AS7-2059
             Project: Application Server 7
          Issue Type: Bug
          Components: CLI
    Affects Versions: 7.0.2.Final
            Reporter: Radoslav Husar
            Assignee: Darran Lofthouse
             Fix For: 7.1.0.Beta1


This is a regression from 7.0.1, present in snapshot.

Lets not reinvent the wheel and lets implement standard console bash-like behavior of autocompletion.

Steps to reproduce:

# type :add-
# press tab
# press tab one more time

Result:
command line shows ":"

Expected result:
command line behaves like normal shell and leaves ":add-" on the command line
