In perl-markdown, a couple of whitespaces at the end of a line are
rendered as a <br /> tag. It does not appear that cl-markdown has
implemented this feature yet. For example, consider the following
input text (note that there are two whitespaces at the end of "First
line"):
First line
Second line
Output from perl-markdown:
==========================
<p>First line<br />
Second line</p>
Output from cl-markdown:
========================
<p>First line Second line</p>
Best wishes,
Hans
