16855 only helps if the files and directories have no properties, is
gcc going to drop all properties, including svn:eol-style?

I don't object to documentation, but you appear to mean more than
simply documenting it; I think you mean that we should guarantee that
it won't change until we bump the wc format. I don't really like that
idea, aside from the implementation difficulties (what happens when
the code and the documentation don't match?) I don't see what the
Subversion project gains by doing it.
