Hmph, it does look easier to read. I think we used to have some
outlier files that indented CPP directives by prefixing spaces in
front of the whole line, but these days we standardized to express
the indentation by inserting spaces immediately after '#' that
always sit at the beginning of line, so what you showed here is a
good example to mimic.
Thanks.
