From cf588f5ea96b7523965ac48bc39e6d9d2dc4e828 Mon Sep 17 00:00:00 2001

Subject: Introduce emms-completing-read.

This allows users to specify which completing-read function to use,
defaulting to ido-completing-read.  The relevant option is
emms-completing-read-function.

Thanks to Thierry Volpiatto for the idea.
