I'm not completely convinced that having more readable .opt and
.trans_opt files is worth introducing a double maintenance problem.
But it's fairly unlikely there will be much maintenance, so it's ok.

write_escaped_string?
Well, it's not very escaped. But in the interested of making it
easy to update both copies, it's probably best to retain this name.

The change is fine.
