Date: Mon, 21 Mar 2016 21:19:04 +0100

Hello,

I try to give a recipe resembling a bug in Magit concerning hidden lines
and cursor movement.  In some buffer (emacs -Q) do


  (insert "111" "\n222\n"
          (propertize "333\n444\n\n" 'invisible t)
          "555\n666\n")

and move around with C-n, C-p.  Then the cursor will appear over the
first "5" but point is actually located inside the invisible area.  This
is the cause of our trouble.

(setq line-move-visual t) helps, but setting (setq goal-column 0) makes
it appear again.

For reference, this is the original report in Magit (including
screenshots):

Thanks,

Michael.
