I guess you are right. All other lowercase envariables have explicit 
descriptions about which programs set them. I suggest to change
"This  is  set  to tell the whatnowproc the user's choice of editor" to
"This is set by comp, repl, forw, and dist to tell the whatnowproc ..."

Do you think this is clear enough?
