Thanks for a pointer; 276358 claims that ce->ce_mode would be zero
for path added with "git add -N path", but I do not think it is
correct.

The updated behaviour is more understandable.  With "add -N", the
user said "Just keep an eye on this path, I cannot decide what the
contents for this path in the index should be at this moment".
grep_cache() that checks the contents in the index cannot say what
is in the index, because the contents is not yet there.
