Thanks for this info. I wasn't aware of this difference, and it's
always good to learn new things (a welcome change in a thread like
this ;-).

So IIUIC, copyright assignments would make the difference between
one "joint authorship" (with assignments) and (single or joint)
authorship for the original author(s) plus "modifying authorship"
for the new contributor(s) (without assignments), but it wouldn't
change the fact that each of the authors can take action on his own,
