Comment #4 on issue 1595 by address@hidden: lilypond-book papersize  
gives margin warnings
http://code.google.com/p/lilypond/issues/detail?id=1595

Using paper size does not solve the problem, AFAICS. We are currently  
obtaining the correct line width from latex/texinfo, and lilypond-book sets  
this width accordingly and passes it to lilypond. There are just a few  
problems:
1) If you give lilypond a line-width of, say, 154mm, the created image WILL  
be larger (the line-width is 154mm, but there is a bar line on the right,  
which can't be cut in the middle, so the image is cropped after the  
barline, adding some space).
2) The other problem is how lilypond handles line-width, paper-size and the  
margins. There is no way to increase the left/right margin for quote by a  
given amount. Rather, one has to give the new margins or line-width in  
absolute values. Now, the problem is that in lilypond-book, we only have  
the auto-detected line-width and nothing else. if paper-size is given, we  
don't really have the paper-width, the margins or the line-width (short of  
hardcoding most paper-sizes and margins in lilypond-book, too). Now, with  
quote we need to increase the left margin by 0.4in... The  
#(set-paper-size...) clears the line-width variable, so we cannot adjust   
an existing line-width, but if we are using auto-detected variables, we  
only have line-width available to adjust. In other words, the handling of  
the quote options needs to be different, depending on whether papersize was  
given or not. Lilypond-book's structure, on the other hand, is designed so  
that each option can more or less be handled independently from the  
others...
