Comment #5 on issue 1356 by address@hidden: LilyPond-style comments embedded  
in a Scheme expression can't include special characters
http://code.google.com/p/lilypond/issues/detail?id=1356#c5

Record $ and # expressions inside of #{ #} for better correlation

This improves and robustifies the closure handling of #{ ... #} and
makes for proper error messages (well, the column display for the
first line of #{ ... environments is missing the start of the line up
to #{, but file and line number are ok).  When the user managed to
confuse Lilypond sufficiently that it has managed to preparse $ and #
closures not actually in the source, Lilypond just reverts to
interpreting the contents straight.

This should fix issue 1356 to the degree where only extremely ugly
input will cause problems.
