And JGit and any JGit derived tool (e.g. EGit, Gerrit Code Review)
will fail horribly and refuse to process that tree, or worse, will
produce incorrect results when fed garbage like an unsorted or
incorrectly sorted tree.

Tree ordering matters. And that niggly bit about subtrees sorting as
though their names end in '/' even though they don't really matters.
