That's a lot of opinion, and not particularly well-founded
opinion at that, given that your code was incorrect to begin
with.

Ibid.  Const qualifying a pointer that I'm not going to assign
through is just good hygiene, IMHO.

>the loop body and half of the termination condition.

I think you're trying to project a value judgement onto that
loop in order to make it fit a particular world view, but I
think this is an odd way to look at it.

Another way to loop at it is that the loop is only concerned
with the iteration over the string, while the body is concerned
with applying some predicate to the element, and doing something
if that predicate evaluates it to true.

That's a way to look at it, but I submit that's an outlier point
of view.

Uh, no.

No, it declares a pointer to a pointer to char.

>(as each pointer in C points to an array)

That's absolutely not true.  A pointer in C may refer to
an array, or a scalar.  Consider,

	char c;
	char *p = &c;
	char **pp = &p;

For a concrete example of how this works in a real function,
consider the second argument to `strtol` et al in the standard
library.

"more characters" is a poor metric.
