That's one of those things I'd really like to try, but will never have
time.  But I can at least file some bugs.

What stopped me from doing so in the past is that the missing things
were really some things I would consider like oddities / inconsistency
of our style.  For example, we use space before parenthesis, except for
the `_` (gettext) macro:

  printf (_("Hello %s\n"), name);

If we tell clang-format we want spaces before function call parenthesis,
it (rightfully) inserts a space after the `_`.  To prevent that, I
suppose we'd need a way to say: in general I want this style, but for
this macro I want this other style.  I fear I'll be called crazy if I
request that :).
