fix links with code with square-brackets

There is a python-markdown bug that causes links containing code with
square brackets to malfunction in certain contexts. Work around the bug
by adding html " " at the end of the line to avoid the issue.

This can be reverted if Python-Markdown bug 1209 gets fixed upstream.
