Make emacs C++ style setting work for me

Make emacs C++ style setting work for me

In the .dir-locals.el file for emacs, instead of setting c-default-style, set c-file-style.  The former was not setting the style for the files I opened.

“Make […] work for *me*” sounds as if this isn’t a general problem? I don’t know
*anything* about emacs (except that vim is superior :P) but googling
c-default-style makes me wonder whether this isn’t only a problem of your emacs
config.

Is it possible that this patch breaks the behaviour for someone else?

I am using Emacs 25.3.1.  My experience was that when c-default-style was set in
the dir-locals, when I would open a lily/*.cc file, c-default-style would indeed
change locally to the value in dir-locals, but the indentation mode of the
buffer was set according to the original value of c-default-style in my emacs
configuration.

The documentation for c-indentation-style says this:

    Name of the currently installed style.
    Don’t change this directly; call ‘c-set-style’ instead, or set the variable
    ‘c-file-style’ in the file’s Local Variable list.

Therefore, I tried setting c-file-style, and now the indentation mode is
correct.
