This is bogus, to the extent that this option probably shouldn't even
exist; please do not recommend using it. If you actually need to copy
from XEmacs to another X application, the above setting will break it.

This is the correct solution for anyone using remote X clients over a
slow link. If you need to copy between XEmacs and other X
applications, you can still use C-insert and Sh-insert.
