[stringtemplate-interest] formatting the last element of a list

[George Berger]

I tried that build, stringtemplate-05-03-2007.15, but got the same
result.  I poked around in the source code that came with it and found
this in ASTExpr.java:

	/** Return all but the last element.  trunc(x)=null if x is single-valued. */
	public Object trunc(Object attribute) {
		return null; // not impl.
	}

Looks like it's not quite all there yet.
