+1.  But why not for all control chars?

I haven't been following this thread - no
doubt I'm not seeing special cases etc.

Currently, `ctl-arrow' controls the display.
That works for me.

And any code that changes the display-table
entry of a char has its intended effect.
Also good.

(Maybe `ctl-arrow' could be extended, to allow
different non-nil values to specify different
representations, including \n and ?\n.  For
compatibility, nil would still specify octal.)
