riched20: add EM_EXSETSEL conformance tests and fixes bug 4462

[Brian Chang]

Hi Dan,

Thanks again for the suggestions. I did indeed run the conformance tests 
on Windows -- passes with no problem. The conformance tests confirm that 
the return value is not the range. Good catch for the limiting of cpMax, 
it simplified the return logic. I also fixed the whitespace violations I 
found.
