New issue 2058 by address@hidden: horizontal spacing allows space for  
neighboring staves in surprising ways
http://code.google.com/p/lilypond/issues/detail?id=2058

The required horizontal space is determined when the score is  
(conceptually) one long unbroken line, and with the lines of Staves,  
Dynamics, Lyrics, etc., tentatively spaced as closely as possible based on  
coarse estimates of the eventual heights of their contents.

The results can appear mysterious, most often in short scores like the  
regression tests.  In the examples below, LilyPond makes different  
decisions about now a lyric should avoid the treble clef, depending on  
other notes that might be on a different line or page. This is, in a sense,  
left over from issue 1229 (comment 13).

\version "2.14"
\paper {ragged-right = ##t indent = 0}
<< \new Staff {g1 \break g'2 r2 \bar"|."}
\addlyrics {go straight } >>
<< \new Staff {g'1 \break g'2 r2 \bar"|."}
\addlyrics {go straight } >>

Started at http://codereview.appspot.com/5354043/ so that the tentative  
spacing of lines mentioned above is based on the ideal, not  
minimum,spacing.  Then the results more often make sense when looking at  
the final output, and short scores more often act like realistically long  
scores.  The lyric above would always go under the treble clef.
