2052 A frame's focus redirection can be changed by `select-frame'. If frame
2053 FOO is selected, and then a different frame BAR is selected, any
2054 frames redirecting their focus to FOO are shifted to redirect their
2055 focus to BAR. This allows focus redirection to work properly when the
2056 user switches from one frame to another using `select-window'.
2058 This means that a frame whose focus is redirected to itself is treated
2059 differently from a frame whose focus is redirected to nil; the former
