The index is not designed to hold tree objects (at least not at this level),
and update-index should be fed only the full path names of files, symbolic
links (mode 120000), or gitlinks (mode 160000).

Whether it's reasonable to ask for the update-index command to
understand that `040000 tree <treeid> <path>` means to insert all
the files *within* the given (existing) tree object, at the implied
constructed paths, I'll leave as an open topic here. :-) But if you
were to do this manually yourself, it should work.
