This is just a try, I can also extract has-min and has-max

@pitrou @wgtmac would you mind take a look whether this fixing is ok or there is better api? I'll draft testing once api is stable

[wgtmac]

I'm fine to be conservative. So this change looks good. However, the encoded_min and encoded_max are still set. I'd propose to deprecate virtual bool HasMinMax() const = 0; and add virtual bool HasMin() const = 0; and virtual bool HasMax() const = 0;

[mapleFU]

Updated: I'll separate the implemetation into two separate patch:

• The first one is test and remove the || in HasMinMax, changing the syntax to both has-min and has-max
• The second one is add HasMin and HasMax.

Anyway this is a bug rather than feature so we should fix it first

@kou @emkornfield @wgtmac would you mind take a look? This patch only change || -> &&
