I don't know anything about power mode, and I'm afraid to say anything because Li Haoyi will point out that Ammonite doesn't suffer from that defect.
scala> val s = """

object $read extends scala.AnyRef {
def <init>() = {
super.<init>;
()
};
def $line = "val s = ";
abc;
" // show";
def $trees = Nil;

val s = "\nabc\n"

Sorry for the spam, but this example offers greater hilarity...
scala> val s = """ abc """ // show
object $read extends scala.AnyRef {
def <init>() = {
super.<init>;
()
};
object $read extends scala.AnyRef {
def <init>() = {
super.<init>;
()
};
def $line = "val s = ".abc(" // show");

It's not subtle. The $line part uses:
private def tquoted(s: String) = "\"\"\"" + s + "\"\"\""
It falls under https://issues.scala-lang.org/browse/SI-9016 perhaps. "More limits of text-based REPL."private def tquoted(s: String) = "\"\"\"" + s + "\"\"\""

Ammonite doesn't support power mode =D so I can't take credit for this one
