Hello all,

When operating on a heading, M-Right/M-Left promotes or demotes one
heading only, and M-S-Right/M-S-Left promotes or demotes an entire
subtree.

When operating on list items however, there is no distinction between
M-Right/M-Left and M-S-Right/M-S-Left. Both key combinations operate
on the current item and on all subitems

Example: No difference between M-Right and M-S-Right on item 1 below:
- item 1
    - item 2
    - item 3

I find this behaviour somewhat confusing.

Attached patch seems to fix that for me.

Kind Regards,

Matti
