It's been done.  (The timestamp on the hardcopy is 02:09 03-Apr-1980, but I
think I must have written it a couple of years before that.)  Actually, I used
/@...@/ for the nestable comment, and implemented a few other "improvements"
that couldn't be done with simple preprocessor abuse.  But I was a C novice
back then, and hadn't noticed that #if...#endif does the job better.

(The other advantage of that notation is that it gave me an excuse to use the
graphic __@/ , which should be familiar to anyone who consulted OLIVER the
Bookie or was a member of the Caltech Odd Hack Committee.)
