[patch] 21.3 terminal.el -- Show help key at prompt

[Jari Aalto+mail.emacs]

I think it would be good if the prompt indicated which key to press to
get help. Here is the patch.

        * terminal.el (te-escape): Show `?' in prompt for help key.

If `?' does something useful, it must be bound to some command
(te-escape-help) in some map (terminal-escape-map).  So instead of a
literal `?' in the prompt, you should look it up:

(format "...%s..."
	...
         (substitute-command-keys "\\<terminal-escape-map>\\[te-escape-help]")
	...)
