  Log Message:
  -----------
  posix: Add '--file' option

This reads a file before entering the command line loop to allow

  Log Message:
  -----------
  chips/avr, chips/atmega, chips/samd21: Return EOF after finishing EEPROM

This causes the parser to return, which will cause it to completely
reset the parse state, cleaning up after indentation or any potential
errors in the EEPROM.
