Thanks. I know all that. My question was about this pair of calls on
X, not about Windows.

I know this as well. But I trust Jan that if he made that change, he
had a good reason for it. I just don't know what was that reason. My
guess is that he wanted to call x-selection-value-internal, instead of
x-get-selection, that's all.

Yes, I know. The very different semantics of x-get-selection-value on
DOS and Windows is because in other situations this is what users
expect from code that calls x-get-selection-value. Again, this is not
what I need help with.
