I'm really late to this thread, but I figured it would do a "good
deed" by letting you know what the problem (and thus the solution) is.

THE ISSUE:

    Essentially, it boils down to the fact that DOS (and later
    Windows), Macintosh, and UNIX all use different EOL
    ("end-of-line") characters.  These are the invisible codes that
    say: "go to the next line."

HOW EMACS HANDLES THE ISSUE:

    You are seeing "..." because EMACS is telling you that there is
    more to the line, but that you aren't seeing it because EMACS is
    not seeing an /UNIX/ EOL character there.

ONE OF THE FIXES:

    To be able to edit the file and see it correctly in (English)
    EMACS use this command:

       M-x set-buffer-file-coding-system

    When it asks for the "coding system for saving file," type
    "undecided-unix" and hit enter.  Test and see if this causes
    problems with the other editors,  and if it does,  you should use
    the same command and type in "undecided-dos" or "undecided-mac"
    (depending on what editor is going to be used on it next) when
    you are finished using EMACS on the file(s).

THE "BEST" SOLUTION:

    You should be able to set up EMACS so that it automatically
    converts these "foreign" (Mac, DOS) EOL characters to something
    EMACS *uses in the buffer*,  but still *saves to disk* the file
    in whatever was the *original* encoding-format.

    I've seen this discussed on the board later,  so I'm sure the way
    to do it is in the EMACS Info system or on Google groups.
