I'd go for a tool, even if it is slightly to moderately different from what
we tend to use. It's not like the GNU style has been updated to cope with
the more recent C++ syntax, so we have some stuff that isn't properly
documented.

The tool would simplify that.

Also, the style of comment we use (/* */) doesn't go well with clang-format
from what I recall. But we can just drop options that deal with comments.
