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?
