bug#9113: 24.0.50; auth-sources: .authinfo versus .authinfo.gpg

[Roland Winkler]

If an authinfo file does not exists and the user has not customized
anything, something like smtpmail will create a new file .authinfo
with the appropriate entry.

I suggest that instead the code should try first to generate a file
.authinfo.gpg and if this fails it should warn the user that Emacs
is going to create a file .authinfo, which can be very unsafe.

In this context, the doc string of auth-sources is, unfortunately,
not too helpful:

  See the auth.info manual for details.
  [snip]
  It's best to customize this with `M-x customize-variable' because
  the choices can get pretty complex."

The default value of auth-sources should be such that the user is,
at least, on the safe side.
