Code formatting in JIRAs

[Antranig Basman]

According to this JIRA documentation, these syntaxes should work, but 
they don't (at least in the main issue body - I think they do in comments)

https://jira.atlassian.com/secure/WikiRendererHelpAction.jspa?section=all

For example, writing
{code}
stuff
{code}

as on http://issues.fluidproject.org/browse/FLUID-4285 just leaves the 
stuff stuck in the formatting.

Do we have some kind of plugin installed on our JIRA that defeats this 
formatting?

Cheers,
A
