Spring Config Hidden

I have been looking at the Spring Integration samples recently:

git clone git://git.springsource.org/spring-integration/samples.git

I got a lttle bit confused when looking at the Spring config in IDEA.
This file looked like this:

     <file:inbound-channel-adapter id="filesIn"                                    directory="file:../spring-integration-samples/input">          <integration:poller id="poller" fixed-delay="5000"/>

Instead of this:

     <file:inbound-channel-adapter id="filesIn"                                    directory="file:${java.io.tmpdir}/spring-integration-samples/input">          <integration:poller id="poller" fixed-delay="5000"/>

I thought it was referring to a relative path instead of what it is actually doing, which is hiding the variable.
This sort of code folding is useful in stacktraces (e.g. 5 hidden internal calls), however, I'm a little dubious of its usefulness in this context.

How do I turn it off (without clicking on each variable to reveal the variable)?
