Hi,
What the hell is with groff's `Bl -bullet'? "+\b+\bo\bo" makes no sense
to me. Do we really need to preserve this behaviour, or can we just use
o\bo as it is right now in the code?
(Cf. the TODO file.)
Thanks,
Kristaps

Hi Kristaps,

I suspect some devices render (or rendered?) that as real bullet
and not just a bold 'o', by printing a bold '+' and a bold 'o'
in the same place. I can't confirm that, though; neither my
VGA glass console (TERM=vt220) nor my xterm (TERM=xterm) does so.
On both devices, it looks just the same as "o\bo". And i don't
have a wire matrix printer around right now. ;-)

Well, it is certainly not critical, and i admit i can't provide
really good reasons for it. On the other hand, it is a gratuitious
difference. What does it cost fixing it? Or is there any downside
when changing to "+\b+\bo\bo"?
Yours,
Ingo

For now, I'm going to just leave it as-is.
The problem is that this introduces a naughty character: the
interstitial \b. The "+\b+" is ok (bold "+"), as is the "o\bo", but the
middle \b is not allowed. And I'd rather not lift the ASCII invariant
from the low-level drivers for now.
