   ### Adding HTML attributes with the IAL extension

   It is possible to add IAL attributes to generated links or images in the following
   format.
 
-      iex(3)> markdown = "[link](url) {: .classy}"
-      ...(3)> Earmark.as_html(markdown)
+      iex(4)> markdown = "[link](url) {: .classy}"

       { :ok, "<p>\\n  <a class=\\"classy\\" href=\\"url\\">\\n    link\\n  </a>\\n</p>\\n", []}
 
   For both cases, malformed attributes are ignored and warnings are issued.
 
-      iex(4)> [ "Some text", "{:hello}" ] |> Enum.join("\\n") |> Earmark.as_html()
+      iex(5)> [ "Some text", "{:hello}" ] |> Enum.join("\\n") |> Earmark.as_html()
       {:error, "<p>\\n  Some text\\n</p>\\n", [{:warning, 2,"Illegal attributes [\\"hello\\"] ignored in IAL"}]}
 
   It is possible to escape the IAL in both forms if necessary
 
-      iex(5)> markdown = "[link](url)\\\\{: .classy}"
-      ...(5)> Earmark.as_html(markdown)
+      iex(6)> markdown = "[link](url)\\\\{: .classy}"

       {:ok, "<p>\\n  <a href=\\"url\\">\\n    link\\n  </a>\\n  {: .classy}\\n</p>\\n", []}
 
   This of course is not necessary in code blocks or text lines
   containing an IAL-like string, as in the following example
 
-      iex(6)> markdown = "hello {:world}"
-      ...(6)> Earmark.as_html!(markdown)
+      iex(7)> markdown = "hello {:world}"
