[emms-help] jack.el and cl.el

[Michael Olson]

I noticed that jack.el requires cl.el, which could be troublesome if
we want to include it with Emacs.  There are several ways to solve
this, so I thought I would check with the list to see which solution
was preferred.

1. Make jack.el use `emms-delete-if' instead of `remove-if-not'.
Also, write an `emms-find-if' compatibility function and put it in
emms.el.

2. Since jack.el seems to originally have been meant to be a
standalone file, make a copy of the `emms-delete-if' function and call
it `jack-delete-if' (or take it as a basis for `jack-remove-if-not').
Also, write `jack-find-if'.
