Heirlooms have additional examine text, rather than being renamed (#41676)

cl coiax
add: Heirlooms are no longer named "Cherry family bag of dice", but
rather their heirloom status can be determined by the owner on examine.

Because names are inherent to an object when anyone looks at it, I feel
it can be somewhat confusing that you can tell that this screwdriver
is a precious family heirloom just because of its name, rather than
because of the significance that someone holds it.

Only the owner of the heirloom receives the special examine text; so I'm sure this could probably be used to bluff ownership of something non-standard, if and when heirlooms become more exotic.

Heirlooms still work in the same way though, mood bonus from holding, mood penalty if you don't have it.
