Why does C-y yank clipboard contents?

    *** Kill and yank now interact with the clipboard under Windows.
    
    This was done by changing the default value of `interprogram-cut-function'
    and `interprogram-paste-function'.  You can get the old behavior by
    setting these to nil, and there is an option on the options menu to do
    this.

I guess the argument was that (young) native windows people would expect
this, rather than using S-Insert, C-Insert.  I certainly prefer the old
behaviour.
