This was only intended as a demonstration of how the two-argument
strcmp function could be implemented already (I initially forgot the
spaces around the 'x's). This would serve as a test for exact
string-wise equality.

If anything, this could mean that there is no reason to spend time on
adding strcmp now. It's all a digression and I agree with everything
you said about it.
