[PATCH] lex: fix <-> in parameter flags

[dana <dana@xxxxxxx>]

fix for this issue:

  % print -r - ${(l<3><->):-}
  zsh: error in flags near position 8 in '${(l<3><->):-}'

this also short-circuits the isnumglob() test for other cases, like <->
inside an array subscript, but it seems like that's fine?
