Of course not.  Please recall this thread is about whether or not
it is possible to disable shell escapes in vi without source.  The
point of Weitzels comments is that is probably isn't.  He correctly
leaves the point open as to whether it's a bug or a feature; and for
the sake of this discussion I will do the same.  The end result is
still "No, it's probably not possible."
