If we want the flag to only be 1 if the window is linked across
sessions, not if it is linked twice into a single session, you will also
need to clear the flag when a window is joined or moved from session B
into a session A where it already exists (assuming it is not already
linked into another session C).
Wouldn't something like this work and be a lot easier?
s = TAILQ_FIRST(&w->winlinks)->session;
TAILQ_FOREACH(wl, &w->winlinks, wentry) {
if (wl->session != s)
return (1);
}
return (0);
