    work around older libedit which fails to append rl_completion_append_character
    
    I failed to find any issue in varnish and failed to find a
    workaround for the code, so change the test to add an additional
    space after the tab-completion.
    
    If anyone has a better solution, please go head. Otherwise I feel
    this is not worth any more time.
    
    The test change, though not being ideal, should not cause any
    harm at least.
    
    Closes #2833
