[does] limit to has v has|have to skirt response activation on doesnt

[tony-kerz]

this p/r aims to eliminate the extraneous (and erroneous) extra message that looks something like:

John Doe doesn't does not exist

due to the "doesn't" directive also matching the "does" directive but with an unintended match pattern (user name = John Doe doesn't)

Thanks @ceci-woodward. And sorry for the earlier lack of responsiveness @tony-kerz :/
