line blocks are broken
Try to create a simple line block, like so:
| 1234 Sesame St. | New York, NY 10001 | tel:555-111-1111 | email@example.com
Note that when this is generated, it all gets crammed on to a single line:
<pre class="line_block">1234 Sesame St.New York, NY 10001<a href="tel:555-111-1111">tel:555-111-1111</a><a href="mailto:firstname.lastname@example.org">email@example.com</a></pre>
If you turn off indentation, it becomes self-evident that it is stripping the white-space where it should be preserved.
This isn't happening to code-blocks, just to line blocks.
