It is the other way round. Opening a file in binary gives you
uninterpreted bytes. The C runtime ( on which lua builds ) is supposed
to translate whatever you os uses for end of line into a '\n'. So a
file "ab\012bc\015de\015\012" is read the same in every OS in binary
mode, but you may have problems (CP/M like CRLF, unixlike LF or
Macintosh(classic, not osx) CR ).
In default (text) mode they could be read differently. Also, normally
it is not a good idea to use binary mode for text files, or viceversa.
