Hi Michael--

Thanks so much for your quick response.  You are correct that I'm
running "M-x shell".  I suppose I'll need to write a bit of code to
toggle the shell path so I can reset it to the local path when I'm
running "M-x shell" locally instead of remotely.  Too bad there isn't
something to set that works only in the tramp context.
