Definitely, current output is wrong.  But as i said, i'm not sure if
it's worth bothering as ties are screwed in general.

Indeed, whatever the output is it shouldn't change because of new skylines.

Do you mean that padding should influence skylines' "magnetism"?
Something like this:
http://lilypond-stuff.1065243.n5.nabble.com/file/n5705597/magnetic_skylines_-_padding.pdf
(i.e. there would be only one setting, which would affect both the
padding and magnetism of the skylines)?
I think it might be a good idea.
