[O] property drawers mysteriously have become right aligned

[Stig Brautaset]

I just noticed that all my property drawers have become 
right-aligned, except the contents _inside_ them, which is still 
where it previously was. All my agenda entries now have their 
start/end markers right-aligned like this. (I only just learnt 
about org-habit.el)

I actually quite like it, as it makes the properties inside stand 
out a bit more, but I would like to know what I did, if anything, 
to make this happen. Also, I don't like that TAB to indent 
immediately such property drawers indents to same column as the 
:END: marker.
