                    no actual value mono on linux returns null instead of
                    Empty String

Test case that tests reading a string registry key that exists but is empty.

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.13)
Gecko/2009080315 Ubuntu/9.04 (jaunty) Firefox/3.0.13

This is a mono on Linux only problem.

Reading a registry key like the following:

<values>
<value name="Test"
type="string"/>
</values>



MyRegKey.GetValue("Test", String.Empty); // returns null on Linux EmptyString
on Windows (in mono and .NET)

I think 'empty' string reg keys should return String.Empty instead of null.

Attached test case showing problem,


Reproducible: Always

Steps to Reproduce:
1. Compile and run attached test program.
2.
3.
Actual Results:  
False
True

Expected Results:  
True
False
