Perhaps that is the best interpretation, but it sure is hard
to put all that into a formal grammar, whereas the original
concept was very simple:

file		::=	binary_file	|	text_file

binary_file	::=	{ byte }*

byte		::=	

text_file	::=	{ text_line }*

text_line	::=	{ text_char }* newline

text_char	::=	<7-bit ASCII character
				excluding NUL and newline>

newline		::=
