Yup, I'm not sure if it was in 0.11 or 0.12 where they changed it so that mining 2 damaged entities would merge the two into a single healthier item.

AFAIK, Tools, Armor and Ammo have always used this behaviour.

Damaged things like turrets actually get put in their own "damaged items stack" so you have stacks of healthy items and stacks of damaged items. Within a damaged items stack the damage is averaged out (i.e. add a 25% hp item to a 75% hp item and you get two 50% hp items), you'll never get less items by combining stacks of damaged items. It is items with durability (rather than hitpoints) which have the merging behavior.

This is already done in 0.15:
