Comment #12 on issue 3504 by address@hidden: \hspace isn't aligned  
properly by \fill-line (caused by fix to issue 3330)
http://code.google.com/p/lilypond/issues/detail?id=3504

Phil, \fill-line does subtract the extent of the text from the line-width  
to figure the total space between words, but does /not/ distribute that  
space evenly.
See the image from the manual, where the underlying \fill-line {Poet  
Instrument Composer} keeps "Instrument" centered on the page.

This behavior did not change with the patch for issue 3330.  \fill-line did  
not change with that patch.

The underlying functions that put stencils in a line were changed: such  
that \hspace always /replaces/ word-space on either side of it.  \fill-line  
does not account for that new behavior when figuring the list of paddings  
between items.

The underlying function 'stack-stencils-padding-list', which is  
undocumented and used within LilyPond only for \fill-line, was changed with  
the patch for issue 3330, so we would try to change it back.

The function 'stack-stencils-padding-list' that takes an explicit list of  
paddings, should probably not have those paddings treated as word-space,  
because we do not want the special treatment of word-space around \hspace  
for items in an explicit list of paddings.
