I was thinking of an ob-C.el customizable variable that is set by
default to some useful list of includes, not file-settable things.
But I'm probably the last person you should ask about what is useful
here. Real users should speak up.

I think augmentation might be nice, but if people are willing to live
with replacement, I'm not going to argue. And if augmentation carries
the day, there always is the vexing question of what to do when you
really *want* replacement, not augmentation.
