Copyright for Phobos to D Foundation

[Seb via Digitalmars-d]

One thing that confused me a lot in the beginning, is that every 
Phobos module has it's own copyright - I am not a lawyer, but it 
sounded for me pretty weird that in theory I could get sued by a 
lot of Oracle-like patent trolls.
I imagine the same effect also for companies when they read a 
different copyright on every module in Phobos.

Now that D foundation finally got its own page [1], it's probably 
time to start this dicussion.
Is it safe to assume that the entire Phobos source code (except 
for the external C modules), belongs to the D foundation?

Ping @WalterBright, @andralex & people with legal experience.
