Repeating values

Right now the spec mentions the following:

	* repeat = yes/no
		repeat the last value of the variable inside the section loop
		if the other variables have more values, if not specified,
		defaults to yes

I'm wondering if it should be extended to allow either repeating of the
last value the variable has, or of the default value. Example:

{{ section sec1 }}
	{{ $foo default="green" repeat=yes }}, {{ $bar }}
{{/section sec1 }}

If $foo has 2 values ("red" and "blue"), and $bar has 4 values ("small",
"medium", "large", "x-large"), then "blue" will be repeated:

	red,  small
	blue, medium 
	blue, large,
	blue, x-large

If we specify repeat=default, though, it would do:

	red,   small
	blue,  medium
	green, large
	green, x-large

Would this be a useful behavior or not?
