potential off by one in parse_arguments

[tinselcity]

In parse arguments in the length check here

            while ((s[i] != '=') && (s[i] != argument_separator) && (i < inputlength)) {

The bounds checking happens after the deref s[i] -so if i == inputlength the deref on the buffer in s will run off the end before the bounds check (i < inputlength)

Thanks @tinselcity.
