Comment #5 on issue 60 by cjlee112: (patch) windows platform needs a 'b'  
flag to indicate binary formats

I discussed this with Marek and we decided on the following implementation:

for Python code, use mode 'rb' for binary files, 'rU' for text files.  The  
U flag is
specific to Python (introduced in Python 2.3) and provides "universal  
newline"
support; i.e. on any platform, it will read all platforms' newline versions  
(\n or \r
or \r\n) as '\n'.  This ought to make our text file reading accept text  
files from
other platforms transparently.

For C code, use mode 'rb' for binary files, 'r' for text files.  According  
to the
fopen() man pages, there is no standard flag for text file mode; that is  
simply the
default behavior.

I will start implementing this for cnestedlist NLMSA, which is the main  
usage that
comes to mind of binary file mode.
