Comment #6 on issue 1290 by address@hidden: Skyline compaction is  
going overboard sometimes
http://code.google.com/p/lilypond/issues/detail?id=1290

Global increase of padding, either vertical (comment 2) or horizontal  
(comment 3), was generally rejected at  
<http://lists.gnu.org/archive/html/bug-lilypond/2010-11/msg00001.html>.

We overlooked in that discussion, however, the fact that horizontal padding  
can be applied to Systems as distinct from VerticalAxisGroup objects (see  
IR 3.2.106 system-interface) :
\score {
\repeat unfold 80 { <c'''-1 e'''-3 g'''-5> c' <c,-1 e,-3 g,-5> c' }
  \layout {
    \context {
      \Score
      \override System #'skyline-horizontal-padding = #2
    }
  }
}
Padding at the System level avoids the unwanted extra space inside systems  
that one gets by applying comment 3 directly.

There is regression, in that System::skyline-horizontal-padding no longer  
affects the layout of systems on a page.  I could not find any evidence  
that anyone took advantage of the old behavior, however, so this remains a  
purely hypothetical problem.
