Edit: the value seems to include the res0: String =
part.
Also, since you said build file, I noticed this doesn't work:

scala> $intp.isettings.maxPrintString = 2000
$intp.isettings.maxPrintString: Int = 2000
I recall that sbt evaluates initialCommands
early, apparently before REPL has a chance to bind $intp
.
But this works:
