New issue 1434 by pnorcks: SVG backend: xml:space="preserve" is needed for  
<text> and/or <tspan>
http://code.google.com/p/lilypond/issues/detail?id=1434

If the value inside <text> or <tspan> has leading or trailing whitespace  
characters, these whitespace characters are removed by default.  This  
behavior agrees with the SVG/XML recommendations.

With LilyPond, we want to *preserve* this whitespace, because any space  
within \markup strings is significant.  We can use the  
attribute "xml:space" with the value "preserve" to make the whitespace  
significant within <text> or <tspan>, but...

There are some cross-application issues; in particular, applications that  
use librsvg render <text> or <tspan> elements in embarrassing ways when  
they use xml:space="preserve".

It would be nice to verify that librsvg is at fault, and if so, file a  
bug.  Then we can move forward with this.
