CHANGES: Fixed some typos in the description of Random.

35:   o Random rewrite       The random functions have been rewritten to ensure security by -  default. random_string() and random() now gets its data directly -  from the operating system random generator, e.g. /dev/urandom on -  unix. This is about half the speed compared with the random_string -  function in Pike 8.0, but is now as secure as the system random -  generator. +  default. random_string() and random() now get their data directly +  from the operating system random generator, i.e. /dev/urandom on +  most unixen.
