`emms-repeat-track' versus `emms-single-track'

Currently, `emms-single-track' is a buffer-local variable; it will only
apply to the playlist in which it is set.

In contrast, `emms-repeat-track' will apply to all playlists if set. I
think that `emms-repeat-track' should be buffer-local as well. But I
will defer changing it for a while (a couple of weeks) to allow people
to write in with different opinions, on the off-chance that someone has
a different use case that makes setting `emms-repeat-track' everywhere
annoying.
