CORREL-function test case for slope dependent results

It looks like the CORREL() -function results depend on the slope.
If the slope of the data is <> 1, the CORRELATION result can not get close to
1.0.
The CORREL() -return much smaller value than 1.0 if slope is close to 0 or
+/-Infinity.
This can be also correct behavior of the function, but it looks strange
that the CORREL() -results depend on the slope.
