This allows API users to peek into the current set of separator
bytes (either the default ":" or specified by the configuration
varaible "trailer.separators"), which is an improvement over
directly exposing the "separators" variable, but in a longer term,
do we need to have some "trailer context" object that holds this
and possibly other global variables like this?

I do not demand such further abstraction in this series, but I'd
prefer to see if we all have shared vision into the future.

Thanks.
