Subject: [PATCH (take 3)] gitweb: Use File::Find::find in git_get_projects_list

From: Jakub Narebski <[email-masked]>
Date: Thu, 14 Sep 2006 21:34:33 +0200

Earlier code to get list of projects when $projects_list is a
directory (e.g. when it is equal to $projectroot) had a hardcoded flat
(one level) list of directories.  Allow for projects to be in
subdirectories also for $projects_list being a directory by using
File::Find.

warning. Check for the current directory to avoid substr outside
