Hi Bastien,

Just to follow up on the error, reverting commit 0ca4092 fixes the bug that
I mentioned in my last email and reverting the fourth hunk of commit
b8c85a1 should fix the bug that you tried to fix with that commit.  Carsten
had added an 'unless (bolp)' condition to the function that controls
inserting new lines outside of headlines to avoid deleting whitespace.
However, so far as I can tell, the other measures Carsten put in place with
that commit made adding this condition unnecessary. Outside of the contexts
where it produces the first bug I mentioned it does not seem to affect
headline insertion behaviour.

Anyway, reverting those commits should get headline insertion to work as
advertised.

All best

Leonard
