zig test: std.testing.expectEqual error message for the expected value is hard to read

[ZapAnton]

The error message about the expected value of the expectEqual is printed too close to the name of the failed test.
For example the following test

const testing = @import("std").testing;

test "failing test" {
    const x = 5;
    try testing.expectEqual(x, 2);
}

produces the following line:

expected 5, found 2test "failing test"... FAIL (TestExpectedEqual)

Maybe a single space could be used after the expected 5, found 2?

Thanks for pointing this out. There were some recent big changes to the testing system (#8686) and I believe previously it made sense for there to be no newline after the failure messages. But now I think all the std.debug.print calls in std.testing need newlines. Should be quite a contributor friendly issue if anyone wants to take it on :-)
