This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit)
 of 2002-07-12 on fluorine
configured using `configure  --libexecdir=/usr/local/lib --without-xpm 
--without-jpeg --without-tiff --without-giff --without-png --without-gif 
--without-toolkit-scroll-bars'
Important settings:
  value of $LC_ALL: nil

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I'm running a shell within Emacs on a linux box.  The shell is rlogged
into another machine (I've tested another Linux box and a SunOs 5.7
box).  I want to find files containing the word 'foo' so I do:

find . -type f -exec grep foo {} \; -print

The bug is that if a file contains a ^M at the end of the line
(e.g. foo^M) and that line matches my grep then Emacs echos a blank
line instead of the grep output. So instead of:

-----------------------------------------
find . -type f -exec grep foo {} \; -print
foo
./bar
-----------------------------------------

I get :

-----------------------------------------
find . -type f -exec grep foo {} \; -print

./bar
-----------------------------------------

This only happens when the shell is on a remote machine, and only
within Emacs 21.2 (normal shells work fine).  I tested this on Emacs
20.7 and the line was displayed without problem.  New bug?
