In the following (unlikely) case, :setl isk+=^_ will not work

:setl isk=!-~,^*,^\|,^\",192-255,^_,_

because "^_" is already there (and kept), and *followed* by "_" (or any
char-range including "_").

That's why I thought "^_" should be removed first and then added again
(to make sure it's at the end).
