Sorry about the confusion!
Looks like I missed that reply.
Some quick clarification though: the first assignment I sent out was for some modifications to shell.el (bug#60385; see also the thread "New Package: sticky-shell" in emacs-devel: I had a package idea and it was mentioned to add it as a feature instead). I then 1) missed the reply from
copyright-clerk@fsf.org, 2) assumed I'd need an additional copyright assignment for the xwidget-patch, as it concerns different files.
Is the first assignment good enough for all subsequent files I change? If that's the case I'll go ahead and sign it and send it back asap. Just wanted to make sure I'm following the correct procedure.
Thanks for walking me through this.
