The main culprit is `org-do-remove-indentation', which doesn't need to
untabify the buffer in order to proceed. I changed that in master. It
should go a long way towards fixing the issue.
Is there any case left to fix? If there isn't, is the current
documentation accurate enough or do you think it needs to be improved?
