Shift-selection: More tweaking
I have changed my mind and turned off shift-selection support again by
default, because it causes confusing behavior, sometimes calling an Org
command and sometimes doing shift selection. The default behavior is
now:
- in special contexts, execute Org commands
- outside special contexts, create an error that will point users to
configure the variable `org-support-shift-select'. Hopefully that
will make them read the docstring and then decide for themselves
what to do.
