No, you didn't miss anything.

It's obviously me, who screwed up the logical thinking.

Originally, I come up with something along the line in 2/2:

	int abbrev = o->flags.full_index ? hexsz : DEFAULT_ABBREV;
	if (!o->abbrev)
		abbrev = o->abbrev;

I couldn't recalled what I wrote, but that logic requires 1/2,
after I come up with 1/2, I re-analysed 2/2 and come up with current
logic.

I failed to re-visit 1/2 to check if it's necessary.
It's all MY fault.

Sorry for wasting everyone's time in 1/2.

Please eject 1/2 from this series.
