 |It didn't work with the nroff -man they supply. It did work with mandoc

It surely works with "tbl FILE|nroff|more" if there is tbl and
nroff.  Or solely "groff -tTascii FILE|more".

 |So my summary of understanding so far:

Yes i think so.  Note that in

  Hello world.$
  $
  This^Iis^Icentered$
  .sp 0$
  This^Iis^Icentered$
  $
  Well,^Ithis^Ialso$
  $
  Hey.$
  This not$

mandoc deviates from groff unless .ta is used as in 

  Hello world.$
  $
  .ta 4 8$
  This^Iis^Icentered$
  .sp 0$
  This^Iis^Icentered$
  $
  Well,^Ithis^Ialso$
  $
  Hey.$
  This not$

Ie better set tabs explicitly.  Now.  I am not an expert, and my
mandoc is very old, things might have changed.

  $ ll $(command -v mandoc)
