No. It does display all your work.
However, as Linus pointed out, if there are automatically merged entries
without conflicts, it will not display them. Which is sane!
And yes, you can hide some modifications by putting the modified file into
the index. But then you did that very much on purpose.

And what exactly do you think is happening when "cvs add" and "svn add"
did _not_ really add the file to the repository, but only a subsequent

I think that it is one major achievement of git to make clear and sane
definitions of branches (which are really just pointers
into the revision graph), and the index (which is the staging area).
