It's documented for emacs mode to try $VISUAL, $EDITOR or emacs in that
order. It doesn't appear to be documented for vi mode, but it's the same,
except it falls back to vi instead of emacs.
http://git.savannah.gnu.org/cgit/bash.git/tree/bashline.c#n861
On my Ubuntu system this has been patched (both for vi and emacs mode) to
also try "editor" before falling back to vi or emacs. "editor" is a symlink
you set to your favorite editor by running "update-alternatives --config
editor" in Ubuntu. This is probably inherited from Debian. As usual with PS
patches, it fails to change the manual page accordingly
The system where it runs nano probably has a patch like that.
