_arguments: normal arg spec with empty action

["Jun T." <takimoto-j@xxxxxxxxxxxxxxxxx>]

If I type

zsh% awk -<TAB>

then it shows the list of options (-F -f -v), as expected.
But if I hit <TAB> again, it does not cycle through the options.

It seems this is caused by the empty action in the spec:
	'1:program text:'
Adding a space ('1:program text: ') does not work.

The following patch fixes the problem, but is this the best way to go?
