bug#19867: c++-mode indentation issues with C++1x initializer lists

Thank you for fixing this. A minor oversight in the committed patch, in cc-align.el:

 351        (skip-syntax-backward " \t([{" (c-point 'boi))

This call should probably use `skip-char-backward`, because `\t`, `[`, and `{` aren't syntax chars.
It currently works by accident because of the ` ` and `(` syntax classes.
