+  #                words) but not in "-ufoo" (one word).
+  # - :regular:    "Not a command word", and command delimiters are permitted.

+  # When the kind of a word is not yet known, $this_word / $next_word may contain
+  # multiple states.  For example, after "sudo -i", the next word may be either
+  # another --flag or a command name, hence the state would include both :start:
+  # and :sudo_opt:.
+  #
+  # The tokens are always added with both leading and trailing colons to serve as

+  # redirection operator, decrement it each iteration, and stall the current state
+  # when it is non-zero.  Thus, upon reaching the next word (the one that follows
+  # the redirection operator and target), $this_word will still contain values
+  # appropriate for the word immediately following the word that preceded the
+  # redirection operator.
+  #
+  # The "the previous word was a redirection operator" state is not communicated
