OK, good point.  Given its description, atoi() is clearly not
*intended* to work that way, but an implementation could do it as a
(not terribly useful) extension.  I probably should have thought
of that approach, but I didn't.

That's a plausible interpretation, but I think the standard is
vague on that point.  It says "Except for the behavior on error".
One could argue that an "error" is any condition in which it
strtol() doesn't set errno.  One could also reasonably argue, I
think, that strtol("ZZZZZZ") is an "error", indicated to the caller
by storing the value of nptr in the object pointed to by endptr
(if it's non-null).  I don't think the standard has a definition
of the word "error".

Agreed.
