Yup; this is an ancient Windows/DOS problem, dating back from behaviour
inherited from CP/M, which only stored file sizes in disk blocks and needed a
mechanism for finding out where the end of a text file was.
You can turn this off if you open files with fopen(..., "rb") or "rb+". The
only operating system that needs the 'b' is DOS, so most people don't bother.
This will also prevent it from converting carriage returns into /r/n sequences.
