[BUG+PATCH] Let _expand preserve array form w/out zstyle glob

[Marlon Richert <marlon.richert@xxxxxxxxx>]

This is the bug:

% autoload compinit; compinit
% typeset -g tst=(a b)
% : $tst^D
expansions
a  b
% zstyle '*' glob no
% : $tst
expansions
a\ b

I would expect the output to be the same, since we're not globbing here.

Below is the fix.
