Thanks! I will include it in with the following line:

write(Term, _D) when is_binary(Term) andalso size(Term) > 100 -> "#Bin";

changed to:

write(Term, _D) when is_binary(Term), byte_size(Term) > 100 -> "#Bin";

(Coding style)

Points to ponder:

Wouldn't it be more useful to truncate long binaries and end
them with "..."?

Shouldn't bitstrings also be handled?
