Bug#3291: AE uses CR and LF

That's not the behavior I see.

1.  When editing a new file or a unix-style text file, ae treats \n 
    line terminators as might be expected from a unix editor.

2.  When editing an existing file which has \r\n line terminators
    (e.g., a file produced by script(1)), ae uses \n line terminators
    for any added lines.  However, ae does not display the or treat the
    \r part of the \r\n line terminators already in the file in any way
    that would alert the user that they're there.  In fact, it seems
    to try to hide the fact that there are \r\n line terminators in
    the file from the user by attempting to handle both \n and \r\n
    line terminators appropriately.

Perhaps you're doing something different than I am.  Could you
let me know exactly how to duplicate this problem as you see it?
(To spare the list the noise on this, it'd probably be best to
Cc: quiet@bugs.debian.org instead of bugs.debian.org).

I think it might be useful to have ae treat the \r part of a \r\n
line terminator just like it treats \r chars encountered elsewhere
(i.e., display them as "^M", and treat them as unrecognized control
chars).  Comments?

I'll try to find time to look into this.
