We should definitely strive for consistency here...  \r and \f for ^M
and ^L is fine by me (although I guess more people are familiar with ^L
than \f).

As for space...  Hm.  It's unfortunate that it's displayed just as a
blank, so displaying it as \s would definitely make sense.  But it also
sounds a bit confusing.  :-/  Could we ... use a different background
colour on the space to indicate that it's there?  I guess that's not all
that easy to interpret, either...
