[O] Sh-ALT-RightArrow behavior has changed to demote only first subheader when subheaders collapsed

[Susan Cragin]

I noticed that the behavior of SHIFT-ALT-RightArrow has changed when the 
subheadings are hidden. 
Before all the subheadings changed at the same level. Now only the heading 
immediately below it does. 
See below for my example. 
This is my ordinary setup for my agenda. However, on the day I am working on, I 
move the date (Sunday 12 January) out to Level 1, so it comes immediately to my 
attention. 
It used to be that I would promote Sunday 12 January to Level 1, and its three 
subheadings (Agenda, TODO and Journal) would promote also, to Level 2. But now 
only Agenda does so.
??
Ditto the reverse, to demote. 
This may be new functionality, or it may be a bug. 
Please note that I have a today-compiled version of both emacs and org-mode on 
my machine.
