C++ syntax highlighting: Multiple parent classes are not syntax-highlighted if there is a line break in between

• OS Version: Mac OS X 10.12.5

Steps to Reproduce:

1. Write the following syntactically correct C++ code:

class SomeClass: public MyClass1,
                 public MyClass2,
                 public MyClass3
{
// Other members and methods and all that stuff.
}

2. See how public MyClass1 is syntax-highlighted correctly. However, public MyClass1 and public MyClass2 are not getting highlighted at all.

This changes when I put all of the parent classes in one line.

Reproduces without extensions: Yes

Instead of creating a new issue I just wanted to add to this one. Similar to this issue, multiple line class inheritance is not being properly treated as expected. In the project that I'm working on, the original authors decided to put the parent class on the next line.

Notice how the 'BasicTurbulenceModel' parent class is not correctly highlighted:

Seems to be an issue of not correctly taking a newline into consideration.

Looks like highlighting of any user defined type is broken or not implemented at all. Shame,

For VS Code this issue has been moved to jeff-hykin/better-cpp-syntax#14

On there I explain why the fix will be difficult. I will still work on a solution though. Hopefully at minimum there can be a fix that will prevent the styles being broken by the multiple lines.
