Re: [PATCH] apply: refuse touching a file beyond symlink

Why does this not kick in when deleting a file? If it is not OK to
add across a symlink, why is it OK to delete?

Hmph, adding

	if (patch->is_delete &&	path_is_beyond_symlink(patch->old_name))
		return error(_("deleted file '%s' is beyond a symlink"),
				patch->old_name);

seems to break t4114.11, which wants to apply this patch to a tree
that does not have a symbolic link but a directory at 'foo/'.
