Right; non-standard behavior (and any non-binary treatment of '\r' 
certainly counts!) should - and I might dare even to say "must" - be 
disabled by default. Although in this case I can't think of any reason 
why you would ever have a '\r' in a shell script (other than as part of 
a line ending). Although if we make any of this optional, then IMO it 
needs to be done the right way, which is to just ignore '\r', at least 
at the end of lines. That way we can ALWAYS read in binary mode, and it 
isn't a major performance penalty.

I suppose this would mean if it is turned on, scripts on textmode mounts 
will actually be faster because we can ignore the textmode.
