9 Builds a command line string from the given array of strings.
10 Each array item is escaped for Bourne shell. All items are then joined together, with a single space in between.
11 This function behaves the same as ruby's Shellwords.shelljoin() function
18 raise(Puppet::ParseError, "shell_join(): Wrong number of arguments given (#{arguments.size} for 1)") if arguments.size != 1
22 raise Puppet::ParseError, "First argument is not an Array: #{array.inspect}" unless array.is_a?(Array)
24 # explicit conversion to string is required for ruby 1.9
25 array = array.map { |item| item.to_s }
