Can you show us the last bits of the file (od -x).

I suspect you are seeing a NL .vs. CR+LF thing.

There may also be a difference in the trailing newline.  Code that
expects a line to end (readline) expect the NL character.  

Here are ways to look at it.

    $ echo -n bark > /tmp/bark
    $ echo  gark > /tmp/gark
    $ wc /tmp/bark /tmp/gark
    0 1 4 /tmp/bark
    1 1 5 /tmp/gark
    $ od -x /tmp/bark
    0000000 6162 6b72
    0000004
    $ od -x /tmp/gark
    0000000 6167 6b72 000a
    0000005
    [mitch@xtl1 one]$
    $ unix2dos /tmp/bark
    unix2dos: converting file /tmp/bark to DOS format ...
    $ unix2dos /tmp/gark
    unix2dos: converting file /tmp/gark to DOS format ...
    $ od -x /tmp/gark
    0000000 6167 6b72 0a0d
    0000006
    $ od -x /tmp/bark
    0000000 6162 6b72
    0000004

    $ echo -n bark > /tmp/bar
    $ wc /tmp/bar
    0 1 4 /tmp/bar
    $ vi /tmp/bar
    $ wc /tmp/bar
    1 1 5 /tmp/bar

See vim's documentation on :filetype
and "set notextmode"... 

But first lets see what the specific problem is.
