Copyright assignment for Emacs sufficient for Emms?

[Yoni Rabkin]

Hello,

I'm the current maintainer of GNU Emms, the Emacs Multimedia System,
(https://savannah.gnu.org/projects/emms/).

I would like to accept patches from a contributor who has already signed
copyright papers with the FSF for past and future changes to Emacs (but
not specifically to Emms.) Are their Emacs assignment sufficient for me
to install their changes, or do I need to ask them to sign paperwork
specifically for Emms?

Note that all past significant contributors to Emms (from before I
became maintainer) have assignments on-file for Emms, Emacs, or
both. Stefan Monnier and I validated as much as in the past because I
requested that Emms be included with Emacs.
