I finally found the problem. After Guido's advice to try another download
(which, by the way, I had already done before), I downloaded it again but
this time with Internet Explorer rather than Netscape. And now the file was
correct. It appears that netscape translates LF to CR,LF on Windows. This
is caused by the fact that the file is served with MIME type text/plain,
which of course is incorrect. Internet Explorer is know to ignore the MIME
types and only look at the file extension, which generally is a bad idea
but saves the file in this case.
I always thought that Netscape would save files downloaded (with
SHIFT/click or RIGHT MOUSE/Save link as...) without translation.
Unfortunately I don't know a way to specify that a file should not be
mangled.
