Run tut code in REPL :power mode

[ruippeixotog]

I'm trying to run tut code within a REPL in :power mode so I can set things like vals.isettings.maxPrintString, which help me customize the tut output. Usually, having scalacOptions in (Compile, console) += "-Dscala.repl.power" makes the REPL start automatically in power mode, but when I do tutScalacOptions += "-Dscala.repl.power" the option doesn't seem to work.

Am I doing something wrong? Is there any other way I can have access to power mode in tut?
