Setting Vim key bindings for the MySQL client

I add these following lines to ~/.inputrc and now the Postgres client, psql, uses Vim keybindings.

set keymap vi
set editing-mode vi

However, this does not work for MySQL. I understand that MySQL no longer uses readline and instead uses editline. I've tried adding the above to ~/.editrc but it still doesn't work.

How can I get Vim key bindings with MySQL?

I'm on Mac OS X 10.9.5 with MySQL 5.6.21 installed via Homebrew.
