The code has been like this since January, 2004. That's pretty dated.
I guess I was just hoping somebody smarter than me [that's not hard] would

Although the following doesn't — slash *CAN'T* ? — save to the kill ring

even attempt to keep track of $READLINE_MARK), I came up with the following
"clever workaround" [read: "gross hack"] to wrangle even bash 3.2 into
