bug#30115: 25.1; cc-mode (C++) : bad indentation on function closing curly brackets

[Gaétan Allaert]

It is about an indentation issue in C++.

The closing curly bracket at the end of the function is wrongly indented
when:
1. at least one base_1 exists (the comma at the end of base_1 is
   required);
2. base_2 is the last call before the opening curly bracket of the
   function;
3. base_2 has only 1 argument that must be a symbol, not a literal or a
   string.

Example:
foo_good::foo_good (int arg_1, int arg_2) :
  base_1 (),
  base_2 (arg_1, arg_2) {
} // good indentation

foo_bad::foo_bad (int arg_1, int arg_2) :
  base_1 (),
  base_2 (arg_1) {
  } // bad identation

Thanks to have a look at this issue.
