 /* 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().

  * By ~2008, OpenBSD 3.4 was changed to survive glibc-like optind = 0
