Sigh, I don't know why I did not see this earlier.  It looks wrong.

Should this be:

if ((cur->helper && strcmp(cur->helper, helper))
	continue; // skip, name doesn't match

if (!strcmp(cur->name, name)) {
 ...

as is, this restriction has no effect in case the requested
name matches?

AI suggests

if ((cur->helper && !strcmp(cur->helper, helper)) &&
   !strcmp(cur->name, name)) {

... but i think thats bogus too.  What to do?

Send v2 or do you want to followup later?
