One problem with names like "str", "string", and "oid" is that it
leads to this stupid pattern:

    struct oid_array *oid;
    oid_to_hex(oid->oid[0], ...);

We know the thing is object name by the pointer variable having the
name oid already---there is no need to repeat we are talking about
oid again with the field name.

So, "str" being consistent with "oid_array" is not necessarily a
plus.

Ultra-concise v[] that stands for value, or e[] that stands for
element, do not share this problem.

One plus about the redundant field name is that it is easier to run

    grep -E -e "([.]|->)oid"

but I do not know how important that is.
