yeah, i understand that instinct. i think dirtrack may be the more
appropriate place, though.

notably, if you look at the patch, it doesn't actually depend on tramp
at all. it uses shell-prefixed-directory-name and
comint-file-name-prefix, which are generic mechanisms in shell and
comint, which dirtrack already depends on.

tramp does use the user's shell and dotfiles on the remote machine,
but still, good points, the instructions needed more details. i use
tcsh with this dirtrack-list:

(set-variable 'dirtrack-list '(":\\([^ :>]*\\)> *$" 1 nil))

try that, and then run tcsh on the remote machine and run this:

set prompt="%m:%~%# "

that gives you a prompt that looks like this:

purgatory:~/foo/bar>
