[PATCH] allow viewvc to get config file from ENV VAR

Hi,

I am managing a cvs/svn/darcs server at work and I add deal a special request 
from my users:

- some want everybody can see their code,
- some want the viewvc be protected by login/password.

Setting up a login/password in httpd configuration is easy, but I can't apply 
same restriction to everybody.

The solution I found is to setup viewvc in different location using different 
configuration to setup only protected repos in each location.

But it is impossible to use same viewvc code and using different configuration 
file as the configuration path is hardcode in script.

So I patched the original script to pass configuration location using an 
envirronement variable and so allowing such thing in httpd.conf:

ScriptAlias /forge-viewvc /var/www/cgi-bin/viewvcf.cgi

<LocationMatch "/forge-viewvc">
        SetEnv VIEWVC_CONF /etc/viewvc/viewvc.conf
</LocationMatch>

The patch is very small:

Any chance to have it included ?
