BTW, if all you want to do is add the class "active" to current links,
rather than using the default block in "link_to_unless_current", you may
wish to simply wrap the "link_to" method and use the "current_page?" method
directly, which I think is a cleaner way to accomplish what you're trying to
do:
def nav_link(name, options = {}, html_options = {}, &block)
if current_page?(options)
html_options[:class] ? html_options[:class] << " active" :
html_options[:class] = "active"
end
link_to(name, options, html_options, &block)
end
