^R was for reprint as you see in stty -a. Useful for remembering what
you've already typed when some background program clobbers your input.

I think it changed in 5.9 or 6.0. Bash has done the history search
thing as long as I can remember.

I often type EDITOR=vi svn commit since svn defaults to an error message
instead of some fallback editor. This has the unfortunate side effect
of breaking all the keybindings until I remember to type set -o emacs.

What works is to set EDITOR in your profile, then set -o emacs. The other
order will result in the shell changing to vi mode.

Or we could all set EDITOR to ed, the STANDARD text editor.
