Fair enough. I don't mind fixing my own code to test using boundp now. But this
is likely to break other code as well. Code that simply tested whether the value
was non-nil as a safeguard must now be changed to test using boundp as a
safeguard instead. A boundp test previously would not have worked (since it was
bound to nil on Windows). 

So whether considered as a bug fix or not, it is an incompatible change, one
that code which uses x-pointer-shape must accommodate. Perhaps the change should
be called out in NEWS.
