[PATCH] running cgit on a shared host

[Max Christian Pohle]

  i ran into troubles using cgit on a virtual/shared host.
  My modification uses getcwd to determine the path,
  where cgit.cgi ist loctated, because my host disallowed
  the modification of bash-enviroment-vars by prepending
  text to any setting I tryed to modify. This made it
  impossible to tell cgit, where it finds 'cgitrc'.
  while this is not thought to be a mainstream patch, it
  worked for me and might be an inspiration for others.
