[CMD] Fix the command echo-er/unparser.

- Use ConOutPuts() instead of ConOutPrintf() for displaying strings that
      are not printf formatted.

- When echo-ing/unparsing FOR command, any possible FOR variables
      present in the FOR parenthesized list (before the "do" part) should be
      substituted as well.
