Hmm, I don't get it.

If I create a file with notepad, containing three readable bytes and a
linebreak and save this on a textmode mounted directory then I see this:

$ wc 123.txt
1 1 5 123.txt

$ od -c 123.txt
0000000   1   2   3  \r  \n
0000005

$ pwd
/perl

$ mount | grep /perl
H:\perl on /perl type system (textmode)

And I see the same result when moving the file to a binary mode mount:

$ wc 123.txt
1 1 5 123.txt

$ od -c 123.txt
0000000   1   2   3  \r  \n
0000005

$ pwd
/tmp

$ mount | grep /tmp
H:\tmp on /tmp type system (binmode)
