Formatter doesn't support trailing conditionals

[Manfred]

When you write something like this:

<section>
  <%= tag.div do %>
  <% end if empty? %>
</section>

You will get the following error:

==> FORMATTED:
<section>
  <%= tag.div do %>
    <% end if empty? %>
==> STACK:
[["section", "<section>"], ["%erb%", "tag.div do"], ["%erb%", "end if empty?"]]

==> ERROR: Unmatched close tag, tried with ["section", "</section>"], but ["%erb%", "end if empty?"] was on the stack

Granted, it's not necessarily the prettiest code, but it's valid in ERB so it could be interesting to support.
