Text you cut from other programs will stop showing up in Emacs when you
press `C-y', since explicit paste commands are required to paste from
CLIPBOARD and not PRIMARY.

I think we save all text that gets killed into the primary selection
regardless of the value of `select-enable-primary'.  If not, that's a
bug.

IOW, when you press C-k at the beginning of a line, Emacs sets the
contents of CLIPBOARD and PRIMARY (what you paste with the middle mouse
button) to the contents of the line.

Then, when you press C-y, Emacs is supposed to look for the value in
CLIPBOARD (and never PRIMARY).

That means the only valid combination is the default, which is to have
`select-enable-clipboard' set to t and `select-enable-primary' set to
nil.
