title: 'data:post-snippet' truncation in blogger
body: <p>Let's say I wrote a post like this on Blogger:
  abc def ghi &lt;div class="pls-exclude-from-snippet"&gt;jkl mno pqr stu vwxyz&lt;/div&gt;</p>
  
  <p>Instead of listing from a to z, I want Blogger to set its data:post.snippet to 'abc def ghi' only (letting Blogger know to stop if it reads the token: a div with class 'pls-exclude-from-snippet'). How do I do that?</p>
