Summary: compiler detecting tests for nullness

Initial Comment:
The compiler complains about the following code:

String s;
s = gv.docString() != null ? gv.docString() : "null";

The error is:

The value if(`!=`(gv.docString(), null))
gv.docString()
else
"null"
 cannot be assigned to s because it might be null.

However, the following code compiles fine:

void bar(?String arg) {
    String s;
    s = arg != null ? arg : "null";
}

Thanks,
Frank.
