When asserting equality of 2 lists with multi-line strings the error message is a bit confusing. Consider code below:

%new-style
%requires QUnit
%exec-class Test

class Test inherits QUnit::Test {

    constructor() : QUnit::Test("Test", "1.0") {
        addTestCase("test foo", \test_foo());
        set_return_value(main());
    }

    test_foo() {
        list l1 = ("hello\nworld",);
        list l2 = ("hello\nmars",);
        assertEq(l1, l2);
    }
}

And the output:

Assertion failure at a.q:17 [Test::test_foo()]
-----
	>> Expected:
	>> 	--------------------
	>> 	list: (1 element)
	>> 	  [0]="hello
	>> 	world"
	>> 	--------------------
	>> Actual:
	>> 	--------------------
	>> 	list: (1 element)
	>> 	  [0]="hello
	>> 	mars"
	>> 	--------------------
	>> Details:
	>> 	--------------------
	>> 	The values of [0] differ:
	>> 	    expected: "hello (string)
	>> 	      actual: "hello (string)
	>> 	--------------------
-----
Ran 1 test case, 1 error (1 assertion, 0 succeeded)

The details are confusing, because there is only the first line of the string. It's probably intended, because I can see that there is a shorten function: https://github.com/qorelanguage/qore/blob/develop/qlib/QUnit.qm#L1082
But is it really necessary to shorten the message?
