[emms-help] But in emms-playlist-set-playlist-buffer

[Ian Dunn]

I noticed a bug in emms-playlist-set-playlist-buffer today. You may be able to replicate it with M-x emms-playlist-set-playlist-buffer when you have two or more playlists open. When I do this, it only gives me the option of one of my two playlist buffers. Upon further inspection, the problem seems to stem from "sort". I couldn't tell you why, but sort destructively -- and unpredictably -- modifies its input to achieve its output.

I took the liberty of fixing emms-playlist-set-playlist-buffer to use the output of sort, rather than relying on the original input. The patch is attached.
