The rule is

  [simple] = TEXT / [prefix] TEXT / TEXT [suffix] / [prefix] TEXT [suffix]

Since the first token "a" is a TEXT but not a NAME=VAL,
the choices are reduced to

  [simple] = TEXT / TEXT [suffix]

As described in my last post, you cannot stop and return
just the TEXT, but must continue parsing since the ">"
could be part of a [redir] (and must be for the entire
command to be syntactically correct).
