They featured in the MAD magazine parts of a misspent youth, and
I liked that bit of Americana. Plus, I was too lazy to come up

Yes, but not within one source file!! And having the "*/" on the same

I try to stick to the format I showed. If forced, the start'o'comment
can go on a line by itself. And then there's a little point about using
comments like "/*--------------------------------*/" to group logically
