    parser: Invalid redirections are run-time, not syntax errors

    This fixes a long-standing bug where
      echo 'echo >&a' | sh
    errors out with
      sh: 2: Syntax error: Bad fd number
    despite the error being on line 1

    This patch makes the error
      sh: 1: Bad fd number: a
    as expected
