CC Mode does not recognize C++ attributes. Just as an example, the
presence of an attribute causes wrong indentation on this example:

struct C {
  C([[maybe_unused]] int x, int y)
  : a(y)
  {}
  int a;
};

The line that begins with the colon should get another indentation
level.

Attributes are described here:

https://en.cppreference.com/w/cpp/language/attributes

In general, considering them part of the following token for indentation
purposes and fontifying with some existing or new face should be enough.

Excellent!

I've committed the enhancement to savannah master (warning: it's not
quite identical to the patches I sent you), and I'm closing the bug with
this post.
