Thanks for this! I'm going to ask a fairly stupid follow-up question.
I put this in my emacs, but it raised this error "void variable tramp-
methods". I thought maybe you had to quote tramp-methods, but after I
did it started raising "Wrong type argument: listp, tramp-methods".
I'm not quite sure where to go from here. If I'm running 22.3.1, I
shouldn't have to have (require 'tramp) at the top of my .emacs,
should I? I added that, for the heck of it, and it started complaining
about other tramp-related variables being undefined elsewhere in
my .emacs file.
Sorry to chump out, hoping for a little more help...
Thanks,
Eric
