I haven't done a careful analysis of extent_at_byteind, but note the
"prior" argument in the call to extent_at_byteind:
while (1)
{
extent = extent_at_bytind (position, object, Qtext_prop, prior,
fl, 0);
if (NILP (extent))
return Qnil;
if (EQ (prop, Fextent_property (extent, Qtext_prop, Qnil)))
break;
prior = XEXTENT (extent);
}
Ie, each extent gets visited once.
