Help with task: GroovyConsole improvement: configurable output area size

[Emilian Bold]

Hello,

I would like to help out with the task listed at
https://helpwanted.apache.org/task.html?72ff9c55

Console.groovy maxOutputChars already has a System.property so I'm not
certain what's required for #GROOVY-3270, perhaps something like:

-    int maxOutputChars =
System.getProperty('groovy.console.output.limit','20000') as int
+    int maxOutputChars = prefs.getInt("outputLimit", 20000)
