bug#19524: 24.4; term.el directory tracking documentation

[Aaron Paden]

The method documented in term.el for tracking your directory doesn't
work or doesn't work for all cases. This is actually a problem I
stumbled on some time ago, but I was reminded of it recently after
trying out fish shell. See:

http://unix.stackexchange.com/questions/70764/get-zsh-to-report-directory-t=o-emacs

The method I found that worked was actually derived from the bash source
code, and is much simpler Here is an example function for fish shell:

function cd
    builtin cd $argv
    if test $TERM = eterm -o $TERM = eterm-color
        echo \032/(pwd) #IMPORTANT
    end
end

I don't need to tell emacs my user or hostname. Actually — doing so
results in tramp errors. Also, the escape used is different than what is
documented.

I've updated the term.el commentary in emacs-26.
