[eric pouech (＠epo)]

This is part X of cmd engine rewrite.

This serie:
- tackles some other variable expansion issues,
- attaches redirections to CMD_NODE (where it belongs)
  (eg. "> foo (IF 1==1 echo a)" is a valid command),
- preparing for next serie.

Next serie will activate he updated lexer and parser.
