A bit of poking around, and I found I can use C-c C-r as a workaround. But... I've been using this system for a few years now, and today is the first time I needed to look for C-c C-r. I'm quite sure in the past, when jumping from the agenda to a specific heading, org would show the heading *and* the next sibling (and hide the others, which is OK with me). But today, magically, in the middle of a session, the behavior changed. I didn't change any customization variables, just, one minute it was fine and the next it wasn't. Such a mystery... hjh
