It's not really "by default" -- more like "by definition", since
there is no way for the program to use something different.  We
used to record non-canonical modes in ancient versions of git,
but I think fsck-objects would warn on objects created that way.

See git-mktree.

That's a bad example -- the tool being too loose.
