Ah, good. :-).  Though we probably need to keep an eye open for Cygwin/X 
specific interaction problems.

Yes, just checked - Both Emacs 22 and 23 merrily do that (to the 
clipboard if set to use the clipboard in the first place). However it 
may have been less noticeable than it has become since the recent 
changes, said recent changes including using the clipboard in more 
situations than before on some platforms.

It is likely possible to do something about it in future, it's a similar 
problem to some other zero-length-region problems that are known to be 
addressable.
