- If defined, the local environment variable "DISABLE_COMMANDLINE_WILDCARD_EXPANSION"

will disable expansion of wildcard patterns passed on the command line.
  Note that if the variable is not set then the global variable
  '__expand_wildcard_args' will provide the defaults for the switch that
  controls whether the wildcard expansion takes place. And after the
  environment variable has been checked, the '__expand_wildcard_args_check'
  function pointer can still be used to override the switch.

 - fstat() now works with "NIL:" and "/dev/null", respectively. Not that
   it returns much useful information, though.
