Hi Bastien,
more feedback:
I just got bitten by this while editing a file with
visible-mode turned on. I was trying to add some text, and the code
would continuously jump to some other position. Took me a while
to figure out.
So I suggest to add a test for
(or (not (boundp 'visible-mode)) (not visible-mode))
before doing anything.
Also, this made me again think that moving point is not a good idea.
