Yeah, we're picky here.

It's clear enough that the "..." is figurative. As picky as I am,
I wouldn't have commented on it. "// ..." or "/* ... */" is more
pedantically correct, but whatever.
(Incidentally, Perl has a "..." operator, nicknamed the Yada Yada
operator, intended to mark placeholder code that is not yet
implemented.)
The "return 0;" is unnecessary but harmless in C99 and later.
As for "const", there's nothing in the above snippet that requires it.
You can probably add a const or two to the argv declaration:
const char *const *argv
but the standard doesn't include "const" in the declaration of argv.
Strictly speaking, adding "const" probably makes the program's behavior
undefined.
