Enabling pretty-printing will make serialization fail with somewhat cryptic error message like:
com.fasterxml.jackson.databind.JsonMappingException: Unexpected IOException (of type java.io.IOException): writeRaw() functionality not available with Ion backend
since default Jackson pretty-printing tries to use writeRaw() to add white-space indentation.
But this will not work (see #245), so code in 2.12 should just ignore pretty-printing setting first, and then can tackle actual implementation for textual Ion for 2.13 or later.
(note: cleaved off #245)
