You are mistaken; from the file attached to the bug report, 'sh 1' and
'ip' appear in the rendering of a pic table. They have nothing to do
with the .SH and .IP man macros.
The pieces of code in question in groff are these, from
src/devices/grodvi/dvi.cc:
void draw_dvi_printer::fill_next(const environment *env)
{
unsigned int g;
if (env->fill->is_default())
g = 0;
else {
// currently, only BW support
env->fill->get_gray(&g);
}
char buf[256];
sprintf(buf, "sh %.3g", 1 - double(g)/color::MAX_COLOR_VAL);
do_special(buf);
}
... and:
case 'p':
{
if (np & 1) {
error("even number of arguments required for polygon");
break;
}
if (np == 0) {
error("no arguments for polygon");
break;
}
moveto(env->hpos, env->vpos);
if (fill_flag)
fill_next(env);
else
set_line_thickness(env);
do_special("pa 0 0");
int h = 0, v = 0;
for (int i = 0; i < np; i += 2) {
h += p[i];
v += p[i+1];
sprintf(buf, "pa %d %d", milliinches(h), milliinches(v));
do_special(buf);
}
do_special("pa 0 0");
do_special(fill_flag ? "ip" : "fp");
break;
}
Do you still think that this is a groff bug? If so, bearing in mind that
I don't know a whole lot about DVI, I'd like to know more about why.
