mandoc: Cleanup, no functional change: Stop trying to keep fill mode

[schwarze@mandoc.bsd.lv]

Log Message:
-----------
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.
