    ctdb-tests: Don't expand octal escapes in unit test output
    
    The echo command in dash expands octal escapes in strings by default
    but the echo command in bash doesn't.  Since the behaviour is
    ill-defined, use printf to handle affected strings.  However, ensure
    that these strings aren't used as format strings.
