I'm not sure about redit and iedit, but my olc has the same problem, and 
it doesn't seem to be as simple as that.  Text descriptions need those 
\r's online, or people who are using terminals that need them see crap 
like a line
           and the next line
                            and so on.  Somebody a while back posted a 
fix for modify.c to leave out the \r's when using iedit and redit.  I 
tried this and got the above problem with certain users.  I think the 
only way to get normal-looking text online, but save the file without the 
^M's is to parse descriptions to remove all ^M's before writing to the 
output file. 

I'm pretty weak on string manipulation so I haven't worked this out yet, 
but I think you could probably reformat the text by changing all ^M's to 
spaces.

For example, something like this:

remove_emms(char *description)
{
  int i;

  for(i = 0; i <= strlen(description); i++) {
    if(*description + i == '\r')
      *description + i = ' ';
  }
}

This is off the top of my head so don't assume it's correct.  I'm gonna 
try it later and see if it takes care of the problem.
