I'm against unconditionally changing the behavior based on the obscure
fact of whether the directory name ends in a slash or doesn't.  That
slash is ephemeral and users may not be aware to its importance, since
the semantics of foo/ and foo is the same more or less.  So if you
want me to agree to the change, please make this behavior optional.
