So if I have this:
line 1
line 2
line 3
and make line 2 invisible, I get:
line 1
line 3
I place the cursor on the l on line 3, and type x, I get:
line 1
xline 3
Now, if I make line 2 visible again, I end up with
line 1
xline 2
line 3
That's hardly what a "normal" user would expect (I consider myself
normal in this case :-)

So if we have
line 1
line 3
from above, place the cursor on l on line 3, and hit C-e, the
cursor is moved to the i on line 3.
Do you say that you think that behaviour is correct ?
