Change the constant expression rule wrt templates.
Change the constant expression rule wrt templates.

There is ambiguity in constant expressions about whether "<" is
an operator or a delimiter.  Previously the rule treated it as
an operator, but this patch makes the rule treat it as a delimiter.
Which is better?  Both are half-wrong, neither occur in VTK yet.
