    Proof-tree-list-fix

    (proof-tree-list-fix x) is a usual ACL2::fty list fixing function.

    Signature
    (proof-tree-list-fix x) → fty::newx
    Arguments
    x — Guard (proof-tree-listp x).
    Returns
    fty::newx — Type (proof-tree-listp fty::newx).

    In the logic, we apply proof-tree-fix to each member of the x. In the execution, none of that is actually necessary and this is just an inlined identity function.
