mandoc: In HTML output, man(7) .RS blocks get formatted as <div

[schwarze]

Log Message:
-----------
In HTML output, man(7) .RS blocks get formatted as <div class="Bd-indent">,
and i can see no reasonable alternative: they do indeed represent indented
displays.  They certainly require flow context and make no sense in phrasing
context.  Consequently, they have to suspend no-fill mode during their head,
in just the same way as other paragraph-type macros do it.  

This fixes HTML syntax errors that resulted from .nf followed by .RS.
