Mao.  When I read that "syntax on" called "filetype on"
internally, I assumed that it would reload the directories, but
apparently not.

Huh.  It also depends on whether you have a system-wide vimrc that
contains "syntax on"... debian doesn't, but I'm guessing that
ubuntu/redhat/etc would.  Or at least, they /might/, so we can't
rely on them not having this.

ok, let's keep the
  filetype off
  set runtimepath+=
  filetype on
version.  People might wonder about it, but it's safe and works.
Maybe some later version of vim will fix the runtimepath issue.  :(
