PATCH to enable reading of \r\n Newlines in md5sum

[David Bridson]

Hi!

I just ran into a problem checking an md5 file with \r\n line endings. md5sum checks for 
\n line endings but not \r\n so, where an \r\n is present, tries to fopen the correct 
filename with a \r appended. Here's a simple patch to fix the problem.

Cheers,
Dave
