Hello, I believe I've found a regression in c-mode's indentation.

Start emacs, create a buffer in c-mode, paste the following code snippet
in, and press C-x h TAB to autoindent the buffer.

void main() {
  struct Foo foo = {
    .a = 2,
    .b = 3
  };
}

Emacs 25.2 indents the code as seen above, whereas Emacs 26.0.50 indents
it as such:

void main() {
  struct Foo foo = {
                    .a = 2,
                    .b = 3
  };
}

The debug information within this message is from the build of Emacs
26.0.50 which exhibits the incorrect indentation behavior.

-Adam
