Actually, it's here (from the diff -u)...

+		unset run_help_orig_cmd
 		eval "run-help-$1:t ${(qq@)cmd_args[2,-1]}"

... so maybe I've missed the point:  it may have been to prevent
$run_help_orig_cmd being seen by run-help-<something>.  However, that seems
unlikely since (i) there's no reason they'd be confused by it (ii) they
might even find it useful.

I'll (finally) commit what's there at the moment and see what happens.
