$ env VISUAL='od -tx1 -c' bash

5.1.8(1)-release
$ if true

I edited in the C-xC-e and C-d so that it would be visible where I
sent those commands.
$ env VISUAL="ed -p 'ed> '" bash
$ if true

if true; then echo yes; else echo no; fi

if true; then echo yes; else echo no; fi
yes

if true; then echo yes; else echo no; fi

if true; then echo yes; else echo no; fi
yes
