Previously there the case the "char *labelfile" is loaded from a file,
but currently it is alwasy a string build on the process. In that
sense, nowadays it is a kind of internal error, which I think is not
supposed to be exposed to users.
So I think we can leave the code alone to avoid back-patching
obstacles. But if we decided to change the code around, I'd like to
change the string into a C struct, so that we don't need to parse it.
