Agree with that.  I'll think about a quick and dirty solution that
only solves the directory tracking problem (we don't need to parse
the whole command line here, just the 0th and 1st arg, maybe that
simplifies the problem a bit).

I'll bring up the discussion about a more general solution after
Emacs 22 is out.
