An original code (correct rendering):

> <https://github.com/magento/magento2/blob/720667e/lib/internal/Magento/Framework/DB/Transaction.php#L49-L60>

A email with the code (wrong rendering: extra empty lines are added, the screenshot is taken in the GMail web interface):

Are you sure there are empty lines there and its not simply that the CSS is a bit off?

The line breaks between the `<li>` tags are preserved because the code is inside the [`<pre>`](http://www.w3schools.com/tags/tag_pre.asp) tag.  
Additionally, each line of code has a bottom padding of 10px:

Now it became even worse: the violet background now covers only a part of the code block:
