Yeh, let's leave it.

Each one gets a line number (since it's a monotonic count), and the
generic code in cppmain.c needs it to know whether to dump a line
marker when dumping the macros.

The line numbers do appear in diagnostics, so it could be useful to
figure out which command line or built-in was causing the diagnostic,
rather than just knowing it was a built-in or command line option.
I quite like it as it is (with today's tweak).  Let's just let the
blank lines be.
