For me it happens even with 'zsh -f':

$ zsh -f
% autoload -Uz compinit
% compinit
% awk -<TAB>

The first <TAB> lists the options, but hitting <TAB> again (or
again and again ...) does not complete options.

Thanks, the following seems to work:

	'1: : _guard "^-*" "program text"'

and I think this is better, because with the style

% zstyle ':completion:*:descriptions' format '%d'

and if _message is used, then

% awk -<TAB>

will print both "program text" and "options", but only
"options" is printed if _guard is used.
