Inline variable

I ran into another oddity with inline variable today. Given a couple lines
of code similar to this:

MyClass c = SomeMethod(with, some, parameters);
return c;

I highlighted c in the return statement and selected Inline Variable, but I
got code similar to this:

MyClass c = SomeMethod(with, some, parameters);
MyClass c1;
return c1;
