Issue keys, wrapped in square brackets [JRA-9] are not linked correctly in quick search results

If a commit message contains an issue key that is wrapped in square brackets, e.g: [JRA-9], the Commit Messages quick search results do not link the issue correctly.
Instead of going to the http://jirahost/jira/browse/JRA-9, the link is simply relative to the FishEye instance. ie: http://fisheyehost/JRA-9 .

This is most likely caused by a combination square brackets clashing with the wiki-rendering and also the hit-highlighting logic applied to search results.

We need to investigate however this is not occurring on the changeset page in FishEye, just the search results.
