Leaving ewiki_auth() alone

If you just need a project internal Wiki or have only a small group of
active contributors, then you will often find it easier to just restrict
your Wiki using your Web servers .htaccess and .htpasswd method instead
(or see "fragments/funcs/auth.php" for the simpler inline solution).

And often your restriction desires may be matched by the two-wrappers method
described in the main README file - one public read-only Wiki view, and one
password-protected access for contributors.

next >> "interfaces"

You cannot modify the ProtectedMode file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the ProtectedMode.Discussion.
