"~" is already handled specially: we pass in a flag to say we're at top
level so just keep going if you find a "/" after a "~".  This is much
easier as once we've seen the ~ we can relax --- no more handling of
individual directories is needed as we're going to apply the exclusion
in one go at the end (hence the suggestion of the new option to prune
directories).  This has always been the documented way in this case.
