FishEye inconsistently renders wiki markup in commit messages.

When viewing the activity stream (activity tap in a repository), wiki markup in the commit message is correctly rendered. For example, a reference to a changeset is rendered correctly in fisheye_wiki_changeset_good.png.

However, when viewing the actual changeset (clicking on the changeset number from the activity stream), wiki markup in the commit message is not rendered (and newlines are eliminated). For example, the changeset markup in fisheye_wiki_changeset_bad.png.
