When $projects_list points to a directory, and git_get_projects_list scans this directory for repositories, there can be generated the following warnings (for persistent services like mod_perl or plackup):

  Variable "$project_maxdepth" may be unavailable at gitweb.cgi line 2443.
  Variable "$projectroot" may be unavailable at gitweb.cgi line 2451.

Those are false positives; silence those warnings by explicitely declaring $project_maxdepth and $projectroot with 'our', as global variables, in anonymous subrotine passed to File::Find::find.

Those warnings do not appear when run as simple CGI script, so test
suite could not catch them.
