described as follows in x-win.el:
;;; Return the value of the current X selection.

In summary, if you set interprogram-paste-function to nil then I think
you have completely severed the connection between the kill ring and
the X selection, and then you will always have to make a conscious
choice between the two. But that seems to be what you want.

Just to be clear, I don't particularly care. I'm mostly just wondering why the behavior mysteriously changed. But your answer sounds like they should have been the same all along. They weren't. At first, Ctrl-y wasn't copying from X. That's the whole reason I started using the other functions in the first place. It sounds like maybe something changed interprogram-paste-function.
