Allow block usage of content_tag outside of ActionView Templates

Can somebody from core take a look at ticket 7857? http://dev.rubyonrails.org/ticket/7857

It is a very simple patch to content_tag to allow its block form to be used in form builders. This would really help me clean up a lot of code. It has tests and applies cleanly.

Without this patch, the block format throws an exception when you try to use it in a form builder.

Applied. Thanks.
