I just looked at the largest MAR file in DCL.  It has 10,000 lines but
many are comments and many are macro definitions.  Not actual VAX

 I would count macro definition bodies in full, and each macro expansion as
one line. After all, macros are code written once and used multiple times,
just like function calls as far as source code is concerned.

That definitely makes sense.
But there are still multiple possible counts:
- lines in files
- non-comment and non-blank lines in files
- non-comment and non-blank and non-continued lines in files

But in the C vs Macro-32 discussion I think it about evens out. C got
more blank lines, but Macro-32 (hopefully!) has more comments.
