No you weren't. The second edition *does* address return from main().
The first two paragraphs (which I don't feel like typing in) on page
26 cover it - the gist of it is that "programs should return status to
their environment." Note the word should is used. I seldom return
anything from main unless I plan on calling the program from some kind
of script.
