It doesn't cater to Windows, it caters to any platform that has a
'system-move-file-to-trash' primitive (which is supposed to know the
location of trash internally), and Windows just happens to have it.
When such a primitive is not available, Emacs moves the file using the
"normal" file I/O, and then it has to know where to move it.
