This should be "No." (same for copies below).

I doubt this works reliably.  You still can access data once you've got
its SHA1 hash, for instance.

I don't think this explanation is necessary.  What does Subversion say?

A simple "Yes." should suffice.

Simply "Yes.".  "git diff" is wrong, it's actually "git diff HEAD".

Have we got any real tool support for this?  This should be "No.".

I don't think this is true.  Is there any command that closely matches
what CVS does?

Isn't Windows support still a bit lacking in terms of performance?
