This will (falsely, AFAIU) tell us that the region is about to be
modified when we return at the point marked below:
/* If we're not starting on an interval boundary, we have to
split this interval. */
if (i->position != s)
{
/* If this interval already has the properties, we can
skip it. */
if (interval_has_all_properties (properties, i))
{
ptrdiff_t got = (LENGTH (i) - (s - i->position));
if (got >= len)
RETURN_UNGCPRO (Qnil); <<<<<<<<<<<<<<<<<<<<<<<<<<<
len -= got;
i = next_interval (i);
}
