[PATCH] ShowForbidden option for mod_autoindex 2.0.x

[Loic Pefferkorn]

Hello,

I wrote this small patch to backport ShowForbidden option of 
mod_autoindex from apache 2.2.x to 2.0.x

The patch is very simple, mainly stolen from 2.2.x source code.

I originally wrote it for a friend who can't upgrade right now to 2.2.x

I hope this may be of interest to someone :)

Cheers,
Loic
