Sorry, it is select.el, not xselect.el, though it looks pretty X 
specific, so I don't think it could be reused directly.

No, that is something different, but lets put this bit off until the 
on-demand clipboard changes, which are going to be major anyway. This 
might all become much simpler once the unicode branch is merged anyway.

That's why I suggested making all utf-16 coding systems (maybe even 
utf-8) mean "use CF_UNICODETEXT". Even I do not understand all the 
subtle differences between them and which is appropriate to use for 
Windows clipboard, so we can't expect average users to.
