[issue6517] Emphasising in the docs configparser.SafeConfigParser over ConfigParser

[Fred L. Drake, Jr.]

Fred L. Drake, Jr. <fdrake at acm.org> added the comment:

Making ConfigParser an alias for SafeConfigParser creates a silent
behavioral change.  An application developer may not realize that
users rely on the "full" ConfigParser anti-glory and end up breaking
their configurations without so much as providing a heads-up in the
application news.

So long as the application developer has to change their code to move
away from ConfigParser, there's a better chance of affected end users
receiving a heads-up.
