That's correct. C89-and-later allows white space (but not comments)
before the leading "#" in a line. K&R C did not.

Yes, that common style is often hard to read. It exists mostly because
of inertia. For example, by default cc-mode insists on jamming the "#"
on the left and I have been too lazy so far to fix that (at least it
should respect the already-existing style).
