writes to stderr:
  
  - `pretty': the old nested style (default)
  - `escapes': uses escape codes to indicate nesting and message
    level; can be processed using `log2xml'
  - `flat': just plain text, no nesting

  These can be set using `--log-type TYPE' or the NIX_LOG_TYPE
  environment variable.
