Cannot you do this with new $export_auth_hook gitweb configuration
variable, added by Alexander Gavrilov in 
   dd7f5f1 (gitweb: Add a per-repository authorization hook.)
It is used in check_export_ok subroutine, and is is checked also when
getting list of project from file

>>From gitweb/INSTALL

  - Finally, it is possible to specify an arbitrary perl subroutine that
    will be called for each project to determine if it can be exported.
    The subroutine receives an absolute path to the project as its only
    parameter.

    For example, if you use mod_perl to run the script, and have dumb
    http protocol authentication configured for your repositories, you
    can use the following hook to allow access only if the user is
    authorized to read the files:

      $export_auth_hook = sub {
          use Apache2::SubRequest ();
          use Apache2::Const -compile => qw(HTTP_OK);
          my $path = "$_[0]/HEAD";
          my $r    = Apache2::RequestUtil->request;
          my $sub  = $r->lookup_file($path);
          return $sub->filename eq $path
              && $sub->status == Apache2::Const::HTTP_OK;
      };

I guess I'd rather use _last_ field, in the event we add project
description to project list file format.
