[man]: Reset more state in `TH` macro.
* tmac/an.tmac (TH): Reset `mE` and `mS` registers from "an-ext.tmac" to
zero upon beginning a new document.
The reduces potential misrendering when batch formatting multiple
documents in the event one of them leaves a synopsis or example "hanging
open" without closing it with a `YS` or `EE` call. (These are unlikely
failure modes for pages that end civilly with a "See Also" section.)
