  SVN rev 219594 on 2011-03-13 09:36:52Z by kib
  
  MFC r219352:
  The execution of the shebang script requires putting interpreter path,
  possible option and script path in the place of argv[0] supplied to
  execve(2).  It is possible and valid for the substitution to be shorter
  then the argv[0].
  
  Avoid signed underflow in this case.
