So you are suggesting I drop this one completely?  You have more M4 
experience than I do, so if you tell me I'm wasting my time trying to 
fix this in AC, I'll probably trust you.  I've already spent quite a few 
hours trying to get this one right.

I could use an "|" in my help text in place of ",".  It won't be 
consistent with the other options, but for now I could view that as minor.
