In case someone is curious, here is an issue on the ERB repo: ruby/erb#4

Found that adding a line break also works:

Doesn't work

<p>
	<% case @request.author_hosted %>
	<% when "yes" %>
	The school <b>has</b> hosted an author before.
	<% when "no" %>
	The school <b>has not</b> hosted an author before.
	<% end %>
</p>

Does

<p>
	<% case @request.author_hosted 
	   when "yes" %>
	The school <b>has</b> hosted an author before.
	<% when "no" %>
	The school <b>has not</b> hosted an author before.
	<% end %>
</p>

Also Does

<p>
	<% case @request.author_hosted -%>
	<% when "yes" %>
	The school <b>has</b> hosted an author before.
	<% when "no" %>
	The school <b>has not</b> hosted an author before.
	<% end %>
</p>
