Unexpected '_'

[Will Oram]

The following bit of code compiles fine in the OS X binary of 2.6.0 
(lines 268, 269, 270):

b2.\p~\startTrillSpan b~ b~
b4\stopTrillSpan \noDynamic csharp2\p~\startTrillSpan_\markup { \italic 
più \dynamic p } csharp2.~ csharp~
csharp4\stopTrillSpan c2~\startTrillSpan_\markup { \italic morendo } 
c2.~ c~

I just tried 2.7.2, and received this error message:

4violino1.ly:269:61: error: syntax error, unexpected '_'
        b4\stopTrillSpan \noDynamic csharp2\p~\startTrillSpan
                                                             _\markup { 
\italic più \dynamic p }
4violino1.ly:269:72: error: unknown escaped string: `\italic'
        b4\stopTrillSpan \noDynamic csharp2\p~\startTrillSpan_\markup {
                                                                        
\italic più \dynamic p }

convert-ly does not notice these bits, so I don't think there's a 
hidden syntax change in 2.7.
