To my understanding, there is no way to "copyright one's work" - in the
terminology of Larry Rosen (and I guess U.S. copyright law), "copyright
subsists". I.e. the creator of some work has copyright, whether he wants
it or not.
Now, the question is, what precisely constitutes "work"? To my
understanding, modifying an existing work creates derivative work;
he who creates the derivative work first needs a license to do
so, and then owns the title of the derivative work.
There is, of course, the issue of trivial changes - "nobody could have
it done differently". However, I understand that the bar for trivial
changes is very, very low; I understand that even putting a comment into
the change indicating what the change was already makes this original
work. Nobody is obliged to phrase the comment in precisely the same way,
so this specific wording of the comment is original work of the
contributor, who needs to license the change to us.

Our contributor's form is such a blanket agreement. You fill it out
once, and then you indicate, in each patch, that this patch falls under
the agreement you sent in earlier.

When we have sufficient coverage from committers, I will move on to
people in Misc/ACKS. You can just go ahead and send in the form
