Actually, there's a semi-twisted argument that the "unknowns" in the
status are actually "added-unknowns".  And if there were a
"removed-unknowns", so that we could do this symmetrically (i.e.
comparing two working trees), it would be legitimate.

Well, unversioned files do have a representation in that output.  It
would be
None, '/file/path/foo', True, (False, False), (None, None), (None,
'foo'), (None, 'file'), (False, False).

So it would certainly be possible to extend _iter_changes_from to
optionally output unversioned files.  It probably doesn't make sense to
have it know whether unversioned files are unknown or ignored.  For one
thing, there's no way to tell the difference between unknown and ignored
files in its output.
