Hi,

This is a small fix in gitweb/gitweb.perl script that I tried to get 
applied long ago.

The current gitweb.perl cgi script generate lots of warnings in the web 
server logs without reason by skipping defined test.

Pull request was done here against "maint" branch :
https://github.com/gitgitgadget/git/pull/617

Pull request was done here against "master" branch if required :
https://github.com/git/git/pull/767

The change patch is attached if required.

May you plz merge my change ?

Best regards
