Dear Kenichi,

Now, I've a tex source file which is written on Microsoft Windows.  When I
open it with Emacs on my Ubuntu Linux, because the linefeed is different between
Windows and Linux/Unix, so the file will have very long lines in it.  Even I
use the *M-q* and *truncate long line* command, I find the Emacs is always
manipulate the file too slowly to tolerate.

But I can open it with gedit and edit it very quickly, is there any tricks
to solve the problem or some bugs in Emacs?

Attached is my tex file.

Is that really a windows file?  The lines are (mostly) separated with CR
(^M), which as far as I know is _not_ the windows line separator, but in
fact the old macintosh line separator.  Emacs normally handles such
files well, but in this case, there seem to be a few lines which use
newline instead of CR, so emacs thinks it isn't a macintosh file either.

I'd suggest just forcing it to use a consistent convention.

Try the following:

   (1) visit the file
   (2) force newlines to be written using CR:  C-x C-m f mac RET
   (3) save the file:  C-x C-s
   (4) kill the buffer:  C-x C-k RET
   (5) revisit the changed file

But I can't input the C-x C-m, when stroking C-x C-m, the minibuffer will say:

==========
C-x RET-
==========

I see, but this command is equivalent C-x RET f on my Operating System.

I do the following to solve this problem:

   (1) visit the file
   (2) force newlines to be written using CR:  C-x RET f mac RET
   (3) save the file:  C-x C-s
   (4) kill the buffer:  C-x k RET

Please notice, not the command you told me: C-x C-k RET, because if I use
this command, I'll meet the following message:

===============
No keyboard macro defined.  Create one? (y or n)
===============	

   (5) revisit the changed file

Why should these differences are exist?

Yes, C-m and RET are different names for the same key.  You can type
either C-m or RET and it means the same thing.

That's a typo on my part -- I mean:  C-x k RET

    Now, I've a tex source file which is written on Microsoft Windows.  When I
    open it with Emacs on my Ubuntu Linux, 

Please do not call our operating system "Linux".  Ubuntu is an example
of a GNU/Linux system, basically GNU with Linux added.  Calling it
"Linux" is denying us the credit for our work.

					   because the linefeed is different between
    Windows and Linux/Unix,

Emacs is supposed to recognize different end-of-line data automatically
and convert.  If that doesn't happen in your case, but sounds like a bug.

Since you provided a test case, we will be able to debug it.  Thanks.

C-m is echoed as RET.  So just go a head by typing the next `f'.
