Ugh. Please don't break the logic with this strange and bogus transformation.

If you really want it to read more idiomatically, try:

    for (; *s; s++)
        if (!isspace(*s))
            return 0;

;-).

Regardless of the loop structure, I find

	*(str)++

especially ugly and confusing.  I'd understand if it were

	*(str++)

but the parentheses pair is unnecessary.

Not using any increment inside isspace(), like you showed, is the
most readable.

Thanks.
