Description

In the case of lilypond syntax errors, it really shouldn't carry on and try and push it through ghostscript. Extracting the error and showing it to the user would be good

e.g. from bug 47534

Processing `.../file.ly'
Parsing...
.../file.ly:14:0: error: syntax error, unexpected \header

\header {
.../file.ly:34:24: error: syntax error, unexpected '}'

I guess if reedy fixes up the mediawiki install and fix GS error 9 all the error message will be invisible. Good question _how_ should the extension notify the user if there's seemingly some useful score output emitted...

Note, the random syntax errors I have made don't have the GS error 9, but instead look something like:

Processing `/tmp/MWLP.ebe90cf9bcc69ad96d400911052e46f2/file.ly'
Parsing...
/tmp/MWLP.ebe90cf9bcc69ad96d400911052e46f2/file.ly:12:1: error: syntax error, unexpected SCM_TOKEN

/tmp/MWLP.ebe90cf9bcc69ad96d400911052e46f2/file.ly:25:24: error: syntax error, unexpected '}'

I'm going to mark wontfix. All the GS status 9 are all the same error (out of memory)
