parser cannot handle braces without newline

[SingingBush]

the following will parse:

matrix {
 8 64 87; 31 34 18 
}

however putting it on one line like this will not: matrix { 8 64 87; 31 34 18 }

this may be fine, will need to check spec or how other SDL parsers handle this scenario

as per comment in linked issue. For a single line the syntax should be matrix {; 8 64 87; 31 34 18 }
