It looks like Sublime Text 3’s C syntax lexer does not like it when there is a newline between the method name and the opening paren.
In the below example, notokay does not get syntax highlighted as a method, and does not show in the Commadn-R “Goto Symbol” output (screenshot attached). I expect this is a result of a regex expecting the paren on the same line.
void okay1();
void okay2()
{}
void okay3(
int foo
) {
}
void notokay
()
{}
void okay4(){}
