Documentation
Non-nil means insert the first line setting Org mode in empty files.
When the function org-mode is called interactively in an empty file, this
normally means that the file name does not automatically trigger Org mode.
To ensure that the file will always be in Org mode in the future, a
line enforcing Org mode will be inserted into the buffer, if this option
has been set.
