/* BSD-derived getopt() functions require that optind be set to 1 in
* order to reset getopt() state. This used to be generally accepted
* way of resetting getopt(). However, glibc's getopt()
* has additional getopt() state beyond optind (specifically, glibc
- * extensions ('+' and '-' at the start of the string), and requires
+ * extensions such as '+' and '-' at the start of the string), and requires
* that optind be set to zero to reset its state. BSD-derived versions
* of getopt() misbehaved if optind is set to 0 in order to reset getopt(),
* and glibc's getopt() used to coredump if optind is set 1 in order
* to reset getopt().
- * Then BSD introduced additional variable "optreset" which
