The jump is exactly what I have experienced and did not quite understood
what is hapenning there. Should it be possible to scroll by pixel into the
'after-string?

I am unaware whether some buffer text can be shown in only one window (the
inverse of hidden overlay with window property).
If so I would insert the newlines as real text and set save hook to remove
them before saving. I would have to fix gotoline and such, but these are of
my least concern now.
I could create a fake buffer with the data instead of comparing the
original file. This would fix some more issues as I'm using persp mode and
planing of a dedicated perspective for ediff.
