New issue 1338 by RalphBugList: Setting spacing alist key individually  
breaks annotate-spacing
http://code.google.com/p/lilypond/issues/detail?id=1338

\version "2.13.36"

\paper {
 annotate-spacing = ##t

 % this style works only if annotate-spacing is off:
 top-system-spacing #'minimum-distance = #20

 % this style works whether annotate-spacing is on
 % or off, but is not a valid workaround since it
 % unsets any alist keys that were previously set:
 %   top-system-spacing = #'((space . 5))
}
