I use the -E compiler option (gcc & msvc) fairly frequently to look at what
the pre-processor is generating.  This code should be readable (or at least
as readable as possible).  A lost of times, macros expand to a huge wad of
code, containing many expressions all on the same line.  This isn't easily
readable, so we should make sure that the generated code contains new lines
where appropriate.

I'm pretty sure that this is what Steven is getting at.
