Function args in JS

[ak--47]

I've noticed the arguments for a function declaration in javascript don't get any special treatment... is this intentional? (I'm using grey tuesday)

I couldn't figure out how to change this in the source:

note how the default themes do it:

I think it's like this:

        <dict>
            <key>name</key>
            <string>Function argument</string>
            <key>scope</key>
            <string>variable.parameter</string>
            <key>settings</key>
            <dict>
                <key>fontStyle</key>
                <string>italic</string>
                <key>foreground</key>
                <string>#FD971F</string>
            </dict>
