From Jeff Cohen:

I checked out from cvs directly on Windows and I ran into another
problem with the project files.  Evidently, the files were initially
checked in on Unix, and the files were transfered to Unix without
converting the CR/LF line endings first.  When checked out on Windows,
cvs converts the files to DOS format, resulting in two CRs for each LF.
