Details:

Terminal devices properly retain spaces when using .na or .nf, but when "groff
-T DRIVER" is used and DRIVER is ps, html, or pdf spaces are not retained
correctly in pre-formatted text. For example, using the following input file:

.nf
>  HH      HH  EEEEEEEEEE  LL          LL           OOOOOOOO
>  HH      HH  EEEEEEEEEE  LL          LL          OOOOOOOOOO
>  HH      HH  EE          LL          LL          OO     OOO
>  HH      HH  EE          LL          LL          OO    O OO
>  HHHHHHHHHH  EEEEE       LL          LL          OO   O  OO
>  HHHHHHHHHH  EEEEE       LL          LL          OO  O   OO
>  HH      HH  EE          LL          LL          OO O    OO
>  HH      HH  EE          LL          LL          OOO     OO
>  HH      HH  EEEEEEEEEE  LLLLLLLLLL  LLLLLLLLLL  OOOOOOOOOO
>  HH      HH  EEEEEEEEEE  LLLLLLLLLL  LLLLLLLLLL  
 
and "groff -T html" this text becomes

OOOOOOOO<p>&gt; HH HH EEEEEEEEEE LL LL OOOOOOOO <br>
&gt; HH HH EEEEEEEEEE LL LL OOOOOOOOOO <br>
&gt; HH HH EE LL LL OO OOO <br>
&gt; HH HH EE LL LL OO O OO <br>
&gt; HHHHHHHHHH EEEEE LL LL OO O OO <br>
&gt; HHHHHHHHHH EEEEE LL LL OO O OO <br>
&gt; HH HH EE LL LL OO O OO <br>
&gt; HH HH EE LL LL OOO OO <br>
&gt; HH HH EEEEEEEEEE LLLLLLLLLL LLLLLLLLLL OOOOOOOOOO <br>
&gt; HH HH EEEEEEEEEE LLLLLLLLLL LLLLLLLLLL OOOOOOOO</p>

where the text should be in a "<pre>" section or spaces should be retained
with "&nbsp;" replaceing the spaces in such a region.
