From b7c6cb5b854ff8adb10e8e855f64b7700e1a3758 Mon Sep 17 00:00:00 2001

Subject: Cleanup, no functional change: Stop trying to keep fill mode state
 locally in the mdoc HTML formatter, rely on the state stored in the nodes
 instead.

Note that the .Bd -literal code is buggy.  Nested literal displays
result in nested <pre> elements, which violates HTML syntax.
But i'm not yet fixing bugs in this commit, i'm merely deleting
code which has no effect.
